SUMMARY Unlike the last lab on RL RC and RLC circuits we measured the frequency characteristics of these circuits We observed the steady-state sinusoidal response of an high-pass RL circuit a low-pass RC circuit and a band-pass RLC circuit PROCEDURE 1041 Steady-State Sinusoidal Response of High-Pass RL Circuit This part of the lab consisted of constructed an high-pass RL circuit shown below in Figure 101 We used the scope to measure the phase and the gain of the circuit Also we used the Gain-Phase meter to measure the phase and the gain of the circuit Figure 101 High-pass RL circuit A Bode plot is shown below from the measurements of the scope gain in dB versus log f and separately phase shift in degrees versus log f 90 Y 90 20logjw -20log 1j w170212 AdBq 0 -90 -b -tan-1w170212 170212 log f 1043 Steady-State Sinusoidal Response of Low-Pass RC Circuit We did the exact same procedure as above except the data was for a low-pass RC circuit This circuit is shown below in Figure 102 Figure 103 Low-pass RC circuit A Bode plot is shown below from the measurements of the gain-phase meter gain in dB versus log f and separately phase shift in degrees versus log f 90 -20log 1j w2500 AdBq 0 -90 -b -tan-1w2500 250 log f 1045 Steady-State Sinusoidal Response of Band-pass RLC Circuit Again the exact same procedure as above was
@Kibin is a lifesaver for my essay right now!!
