Define the terms fundamental frequency, spectrum, and absolute bandwidth of a signal. A signal has a fundamental frequency of 1000 Hz. What is its period? Assume the signal has a peak amplitude of 1 Volt and that the instantaneous power is equal to the square of the voltage, then compute the average power of the fundamental frequency component of the signal. When the signal is transmitted, the measured power at the receiver is 0.25 W. Express the power loss in decibels.
Given R = 50Kohm and C = 100nF what is the frequency of oscillation Given a required frequency of oscillation of f = 10kHz and R = 8kohm, what should the value of C be

A 10 cm length of a K-band copper waveguide is filled with a dielectric material with er = 2.55 and tan f = 0.0015. If the operating frequency is 15 GHz, find the total loss through the guide and the phase delay from the input to the output of th..
A sinusoidal signal described by Cos (2pit+pi/4) passes through a linear time invariant (LTI) system that applies a gain of 2 and a time delay of 0.125 seconds to the signal. Write the mathematical expression that decribes the signal that will com..
The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.
