I need help with this problem and an explanation of the solution for the image described below. (Introduction to Signals and Systems)

If a DC source (frequency equal to zero) was used instead, what should be the ideal resistor and inductor voltages in a series RL circuit? Support through your answer by providing a computation. If a DC source (frequency equal to zero) was used instead, what should be the ideal resistor and capacitor voltages in a series RC circuit? Support through your answer by providing a computation.

A nonperiodic composite signal has a bandwidth of 170 kHz, with a middle frequency of 120 kHz and a peak amplitude of 20 V. The two extreme frequencies have an amplitude of 10 V. 1. The lowest frequency is KHz. 2. The highest frequency is KHz. Draw the frequency domain of the signal. (You don't need to submit the curve to the Canvas.)
