![]() ![]() Transfer Function A two-port circuit is characterized by its transfer function, whose magnitude is defined as e Vout and Vin are phasor voltages. For example, if the frequency, f, of the ordinary power line voltage in the U.S.is 60 Hz, then the associated angular frequency, w, is 377 radians/s (2圆0). The angular frequency is related to frequency, f, measured in Hertz, by w 2nf. 2) where the voltage source produces the input voltage Vin and the output voltage Vout appears across resistor R.ĬR Figure 2: A two-port circuit Figure 1: An RC filter with a series capacitor and output resistor R Recall that we customarily represent an AC voltage as a periodic function of time, such as V(t) = Vocos(wt) where VO is the amplitude of the voltage, t is time, and w is the angular frequency, whose units are radians per second. This circuit is termed a two-port circuit (Fig. ![]() This time interval is called the half-life, T1/2, and is given by the equation (In2), so T=T12/1n2 = T1/(0.693) Figure 1-Discharge of a Capacitor RC Filter Characteristics Figure 1 below shows an RC filter connected to a sinusoidal voltage source. It can be found indirectly by measuring the time required for the voltage to fall to V. For this reason it is called the time constant, which we call t (tau). When the same capacitor discharges through the same resistor, Vſt) - V.e- The product of the resistance and capacitance, RC, governs the time scale with which the changes take place. Use Multisim to simulate the RC filter behavior Background and Theory Resistance-Capacitance Circuits Theory (see textbook) shows that for a capacitor, C, charging through a resistor, R, the voltage across the capacitor, V, varies with time according to: Vit) - V.
