Question

1. As a reference, observe the full amplitude range of the AC voltage, without limiting. R1 330 0 f=1.0 kHz 3.0 k2 out Vap = 15.0 V Figure 1. AC Circuit without limiter Construct the circuit of Figure 1. Set the function generator for a sine wave with a frequency of about 1 kHz. Begin with the AC input voltage adjusted to its minimum value, approximately 0 V. Connect Channel 1 of the oscilloscope to observe the AC input voltag voltage across R2. e and Channel 2 to observe the output Vary the AC voltage from minimum to maximum and return to minimum. Observe that the peak-to-peak amplitude varies from about O V to about 20 V, continuously and without limiting or distortion. Set the AC input voltage for Vpp 15.0 V. With the oscilloscope set for DC couplin the positive and negative peak values of Vout. Compare with the expected values, previously calc ng, measure and record calculated Table 1. Unlimited AC Voltage Expected values Measured values Vpp input (V) Vpp output (V Vp positive (V) Vp negative ) 15.04-6V 01-13-2 2
