The $R C$ high-pass filter shown in Figure $P 33.53$ has a resistance $R=0.500 \Omega$ and a capacitance $C=613 \mu \mathrm{F}$ . What is the ratio of the amplitude of the output voltage to that of the input voltage for this filter for a source frequency of 600 $\mathrm{Hz}$ ?

Key Concepts

Transfer Function

The transfer function of a filter describes the ratio of the output voltage to the input voltage in the frequency domain. For an RC high-pass filter, this function incorporates the impedance of both the resistor and the capacitor, and it provides insight into how the circuit attenuates or passes signals at various frequencies.

Frequency Response

The frequency response of a circuit details how its output amplitude and phase vary with frequency. In the context of an RC high-pass filter, understanding the frequency response is essential for determining at what frequencies the filter will allow signals to pass unimpeded and at which frequencies the signals will be significantly attenuated.

Impedance in AC Circuits

Impedance extends the concept of resistance to alternating current (AC) circuits, incorporating both resistance and the frequency-dependent reactance from capacitors and inductors. In a capacitor, the impedance (or reactance) is inversely proportional to the frequency, which plays a critical role in determining how the circuit responds to different frequencies.

RC High-pass Filter

An RC high-pass filter is a circuit that combines a resistor and a capacitor to allow high-frequency signals to pass while attenuating lower frequency ones. The capacitor’s impedance decreases with rising frequency, which means that at high frequencies, the capacitor effectively short-circuits the resistor, resulting in most of the input voltage appearing across the output.

Angular Frequency

Angular frequency, denoted by ? and defined as ? = 2?f (where f is the frequency in Hertz), is used in AC circuit analysis to relate the time-varying behavior of voltages and currents. It is a fundamental concept when analyzing the behavior of reactive components like capacitors in filters.
