Final answer:
To generate and plot 3 cycles of the given signal, calculate the values of x[t] for different values of t within one period of the signal, and then repeat this process for two more periods. Plotting these values against t will yield the desired signal.
Step-by-step explanation:
To generate and plot 3 cycles of the signal x[t]=16sin(150πt−45ᵒ) using a simulation frequency of 94000 Hz, we need to determine the values of t for each cycle. One cycle of a sinusoidal wave is completed when the angle inside the sine function goes from 0 to 2π. Since the frequency of the signal is 94000 Hz, one cycle will be completed in t = 1/94000 seconds. We can then use this value of t to calculate the values of x[t] for 3 cycles.
For example, for the first cycle, we can calculate the values of x[t] for t = 0, t = 1/94000, t = 2/94000, ..., t = 1/47000. Plotting these values against t will give us one cycle of the signal. Similarly, we can repeat this process for the second and third cycles to generate and plot the complete signal.
Since the frequency of the signal is 94000 Hz, the time period of each cycle is T = 1/94000 seconds. To generate 3 cycles of the signal, we need to generate and plot 3 periods of the signal, which is 3 x (1/94000) seconds.
