The transfer function can be written as
The transfer function H(ω) of a circuit is the frequency-dependent ratio of a phasor output Y(ω) (an element voltage or current) to a phasor input X(ω) (source voltage or current). Thus,
Vo 1/ jωC 1 H (ω ) = = = Vs R + 1/ jωC 1 + jω RC

where ω0 = 1/RC. At ω = 0, H = 1 and φ = 0. At ω = ∞, H = 0, and φ = − 90°. Also, at ω = ω0, H = 1/ 2 and φ = − 45°.
14.1 INTRODUCTION
In our sinusoidal circuit analysis, we have learned how to find voltages and currents in a circuit with a constant frequency source. If we let the amplitude of the sinusoidal source remain constant and vary the frequency, we obtain the circuit’s frequency response. The frequency response of a circuit is the variation in its behavior with change in signal frequency. The sinusoidal steady-state frequency responses of circuits are of significance in many applications, especially in communications and control systems.

Steps to Apply Superposition Principle:
1. Turn off all independent sources except one source. Find the output (voltage or current) due to that active source using nodal or mesh analysis. Repeat step 1 for each of the other independent sources. Find the total contribution by adding algebraically all the contributions due to the independent sources.
4.3 Superposition (迭加)
Superposition is based on linearity
The superposition principle states that the voltage across (or current through) an element in a linear circuit is the algebraic sum of the voltages across (or currents through) that element due to each independent source acting alone

电路原理英文教材Circuit Principles1. Introduction to CircuitsA circuit is a closed loop that allows the flow of electric current. It consists of various components such as resistors, capacitors, inductors, and voltage sources. This section will provide an overview of circuit principles.2. Basic Circuit ElementsThere are three fundamental circuit elements: resistors, capacitors, and inductors. Resistors impede the flow of electric current, capacitors store and release electrical energy, and inductors resist changes in current. This section will discuss the properties and behavior of these basic circuit elements.3. Ohm's LawOhm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance. This section will explain Ohm's Law and its applications in circuit analysis.4. Series and Parallel CircuitsSeries circuits have all components connected in a single loop, while parallel circuits have multiple paths for current flow. This section will discuss the properties of series and parallel circuits, including their voltage and current relationships.5. Kirchhoff's LawsKirchhoff's Laws, including Kirchhoff's Current Law (KCL) andKirchhoff's Voltage Law (KVL), are essential for analyzing complex circuits. KCL states that the sum of currents entering a node is equal to the sum of currents leaving it, while KVL states that the sum of voltages in any closed loop is zero. This sectionwill explain how to apply Kirchhoff's Laws in circuit analysis.6. Circuit Analysis TechniquesThere are various methods for circuit analysis, such as nodal analysis, mesh analysis, and Thevenin's and Norton's theorems. This section will introduce these techniques and provide examples of their applications.7. Frequency AnalysisCircuits can behave differently at different frequencies. Frequency analysis helps understand how circuits respond to different input signals. This section will cover concepts like impedance, reactance, and frequency response.8. Transient AnalysisTransient analysis examines circuit behavior during the transition from one steady-state condition to another. It involves studying capacitive and inductive effects on the circuit's response. This section will explain how to analyze transient circuits.9. AmplifiersAmplifiers are essential components in electronic systems that increase the amplitude of signals. This section will provide an overview of amplifier circuits, including common amplifier configurations and their applications.10. FiltersFilters are circuits that selectively allow or block certain frequencies. They are used in various applications, such as signal processing and communication systems. This section will discuss different types of filters, including low-pass, high-pass, band-pass, and band-stop filters.11. OscillatorsOscillators generate periodic waveforms without an input signal. They are widely used in applications such as electronic clocks, radio transmitters, and audio signal generators. This section will explain the working principles of oscillators and different oscillator circuits.12. Digital Logic CircuitsDigital logic circuits use binary signals to perform logical operations. They are the building blocks of digital systems such as computers and calculators. This section will introduce basic digital logic gates and their applications.13. Power ElectronicsPower electronics deals with the control and conversion of electrical power. It has applications in areas such as power supplies, motor drives, and renewable energy systems. This section will cover power electronic devices and their operating principles.14. Troubleshooting and SafetyThis section will provide tips for troubleshooting circuit problems and ensuring safety while working with circuits.
