Specify the aliasing frequency of a signal that has a maximum
frequency of 92kHz and a sample frequency of 130kHz. Is this an
optimal sampling frequency? If so, explain why? If not, propose an
optimal sampling frequency.

possible equations in the study of signal generators.
3.
List and explain with the use of diagrams types of signal
generators.
If signal x(t) has a maximum frequency (wm1)and signal y(t) has
a maximum frequency (wm2)where wm2>wm1, determine the Nyquist
rate for each of the following signals:
(a)x(t)+ x(t-1)
(b) dx/dt
c) x(t)y(t)
(d)x(t)*y(t)
A capacitor is connected to an ac generator that has a frequency
of 3.2 kHz and produces a rms voltage of 1.3 V. The rms current in
the capacitor is 29 mA. When the same capacitor is connected to a
second ac generator that has a frequency of 5.1 kHz, the rms
current in the capacitor is 86mA. What rms voltage does the second
generator produce?
1.) Explain the difference between a time domain signal and a
frequency domain signal.
2.) When would you select the frequency domain signal over the
time domain signal.
