A test circuit diagram for measuring the input impedance of a
50Hz notch trap is shown in Figure 1.1. The signal source generates
a sinusoidal signal with a frequency of 30Hz, and oscilloscope
channel 1 probe and channel 2 probe are used to test the ground
waveform of two places marked CH1 and CH2 in the figure
respectively. The test results are shown in Figure 1.2.
Calculate the input impedance of the circuit as seen from the
dotted line based on the test results.
