CR active filters find extensive use in communications and instrumentation measurements. ) By considering how the capacitor impedance in Figure 1 varies with frequency, explain if the circuit in Figure 1 acts as a low-pass or high-pass filter. ) Derive the closed-loop gain for the case of very high frequencies. ) Draw a graph that shows the frequency response of the CR active high-pass filter. The y-axis should correspond to gain in dBs and the x-axis to frequency. Make sure that you clearly indicate the 3 dB point and the equation that describes the relationship between w and CinRin at the cut-off frequency. Cin Rin R A Vin Vout Figure 1
