Question

Please answer in detail

A) Assume that x(t) -2 sin (4 pi t)-2 input is applied to a high pass filter with the cut off frequency of 2 Hz. Explain in detail with appropriate justification and accurately sketch the output voltages that appears on the oscilloscope screen if 1 volt/div and 0.25 sec. time/div are set. + B) Assume that x(t) 4 cos (2 pi t)+4 input is applied to a low pass filter with the cut off frequency of 1 Hz. Explain in detail with appropriate justification and accurately sketch the output voltages that appears on the oscilloscope screen if 2 volt/div and 0.5 sec. time/div are set. +
