Are these Network Analysis handwritten notes free?

Yes. Fill in the short form on this page and the PDF downloads right away. There is no fee for the notes.

Are these official university notes?

No. These are original Uncodemy revision notes for Network Analysis. They are not issued or approved by AKTU or any other university, and they are not past papers.

Which syllabus do they follow?

They follow the common B.Tech syllabus for Network Analysis used by most Indian universities, including AKTU and colleges on the AICTE model curriculum. Unit order and depth differ, so match the notes with your own university syllabus.

Is this the same as Network Analysis and Synthesis?

Mostly yes. Many universities call the subject Network Analysis and Synthesis or Circuit Theory. Synthesis topics such as Foster and Cauer forms may need extra reading if they are in your syllabus.

Do the notes include two-port networks?

Yes. There is a full unit on Z, Y, h and ABCD parameters, their conversions and the reciprocity and symmetry conditions.

About these handwritten notes

These Network Analysis notes are original Uncodemy revision notes, written in a clean handwritten style so they are quick to read before an exam. They follow the common B.Tech syllabus for Network Analysis (B.Tech ECE and EEE, and GATE EC basics). They are not official university notes and not copied from any textbook or past paper.

Topic order, unit numbers and depth vary between universities, so first place each unit below against your own university syllabus. If your syllabus has a topic that is missing here, add it in the margin from your class notes or textbook. Use these notes for revision after you have studied the topic once in class, not as your only study material. They are short on purpose: the aim is to help you recall the main ideas, formulas and diagrams quickly, so that your exam time goes into writing good answers.

What's inside the Network Analysis notes

The notes build from simple DC circuits to network functions and two-ports. Each unit has the method in steps, a formula box and a solved example.

Unit 1: Basic Concepts. Element relations for R, L and C, and independent and dependent sources.
Unit 2: Network Laws and Analysis Methods. KCL and KVL, nodal vs mesh analysis, supernode and supermesh, and star-delta conversion.
Unit 3: Network Theorems. Superposition, Thevenin, Norton, maximum power transfer, reciprocity and Millman's theorem.
Unit 4: Transient Analysis. First-order RC and RL circuits, time constant, and overdamped, critically damped and underdamped series RLC responses.
Unit 5: Sinusoidal Steady State and Resonance. Phasors, impedance, series and parallel resonance, Q-factor and bandwidth.
Unit 6: Network Topology (Graph Theory). Graph, tree, incidence, tie-set and cut-set matrices.
Unit 7: Laplace Transform in Circuit Analysis. Transformed circuits, network functions, poles and zeros, and Hurwitz polynomials.
Unit 8: Two-Port Networks. Z, Y, h and ABCD parameters, conversions, and reciprocity and symmetry conditions.
Unit 9: Filters and Coupled Circuits. Basic filter types, mutual inductance and the dot convention.

The last page of the PDF lists the most asked practice questions for the whole subject, so you can test yourself after finishing all the units.

Formulas and solved examples in the PDF

Formula boxes cover the time constant, RLC damping conditions, resonant frequency, Q and bandwidth, maximum power transfer and two-port conversions. Solved examples include a Thevenin and maximum power circuit, RC charging, series resonance and the ABCD matrices of a series impedance and a shunt admittance.

How to revise Network Analysis with handwritten notes

Handwritten-style notes work best when you read actively. Keep a pen and a rough notebook beside you, cover the formula or diagram, and try to write it yourself before you look.

For every theorem, write the method as three or four numbered steps and solve one circuit with them.
Practise at least two circuits with dependent sources. They are where most students lose marks.
For transients, always find the initial value, final value and time constant first, then write the response.
Make one table for two-port parameters with the reciprocity and symmetry condition for each.

In the last week, read only the formula boxes and exam tips, and solve one numerical or long question per unit from memory. If you study with friends, ask each other to explain one diagram or derivation aloud. Explaining a topic is the fastest way to find the gaps in it.

A short revision plan

If your exam is about a week away, this plan covers every unit in the PDF once and leaves time for practice. Stretch it over two weeks if you are starting from scratch.

Day 1: Basic Concepts, Network Laws and Analysis Methods.
Day 2: Network Theorems, Transient Analysis.
Day 3: Sinusoidal Steady State and Resonance, Network Topology (Graph Theory).
Day 4: Laplace Transform in Circuit Analysis, Two-Port Networks.
Day 5: Filters and Coupled Circuits.
Day 6: Solve the practice questions in the exam focus section below, one per unit, without the notes.
Day 7: Read only the formula boxes and exam tips, redo the numericals you got wrong, and sleep early.

Common mistakes to avoid

Switching off dependent sources when finding Rth. Keep them and use a test source instead.
Taking the inductor current or capacitor voltage as zero at t = 0+ when it was not zero at t = 0-.
Using RL = Rth for an AC circuit. For full matching, ZL must be the complex conjugate of Zth.
Mixing up the ABCD sign convention for I2 when checking reciprocity (AD - BC = 1).

How Network Analysis links to other subjects

Network Analysis uses differential equations and the Laplace transform from Engineering Mathematics. It is the base for Analog Electronic Circuits, Control Systems, Signals and Systems and Power Systems, all of which use the same circuit methods.

Exam focus: high-weightage topics

University papers usually give the most weight to network theorems, nodal and mesh analysis, first-order and RLC transients, resonance and two-port parameters. Graph theory matrices and Laplace-domain analysis are common medium-length questions.

Typical long and numerical questions to practise:

State and prove Thevenin's and Norton's theorems with an example.
Derive the maximum power transfer condition and explain why efficiency is 50% at that point.
Solve a circuit with a dependent source using nodal and mesh analysis.
Find the transient response of an RC and an RL circuit after switching.
Derive f0, Q and bandwidth for series resonance.
Find the Z, Y, h and ABCD parameters of a T or π network.

When you write a long answer, start with a one-line definition, draw the diagram or circuit, write the derivation in clear steps and end with the final result and its unit. For numericals, write the formula first, then substitute, so you can still earn step marks if the arithmetic slips.

These are practice questions based on common syllabus topics. They are not verified past papers, and we do not claim any question will appear in your exam. For real previous papers, use your university's official archive.

Who these notes are for

These notes are for B.Tech ECE and EEE students preparing for their Network Analysis, Network Theory or Circuit Theory semester exam, and for students revising GATE EC and EE basics such as Thevenin with dependent sources, transients, resonance and two-port conversions. First-year students can also use the theorem units alongside Basic Electrical Engineering.
