Let's break down the steps for the given questions:

1.o	b. Plot the signal ?: This is a time-reversed signal, which flips the signal about the vertical axis (t = 0).Period and Frequency of Periodic Signals

For this part, I will need the mathematical forms of the periodic signals you're referring to. Could you provide these so that I can help you determine their period and frequency?Signal Period Calculation

	o	A sinusoidal signal completes 80,000 cycles in one minute.of a signal is defined as the number of cycles per second (in Hertz, Hz).You are asked to plot two transformations of this signal:

	o	a. Plot the signal ?: This represents a time-shifted signal.To generate these plots, I'd need the mathematical form of the signal ?.o	The frequency ??2.3.
