Question

Draw the following 4 signals where A=2 and fF=1MHz

Please select timescale from -1 to 1μ sec and draw using Matlab on a 4 by 4 grid using subplot (2,2,n) where n is 1,2,3 and 4 for a(t), b( t),c(t) and d(t), respectively.
a(t)=A/2+(4A/π)cos(2πfFt)
b(t)=A/2+(4A/π)cos(2πfFt)−(4A/3π)cos(2π(3ff)t)
c(t)=A/2+(4A/π)cos(2πfFt)−(4A/3π)cos(2π(3fF)t)+(4A/5π)cos(2π(5fF)t)
d(t)=A/2+(4A/π)cos(2πfft)−(4A/3π)cos(2π(3fF)t)+(4A/5π)cos(2π(5fF)t)−(4A/7π)cos(2π(7fF)t)

Answer 1

The signals a(t), b(t), c(t), and d(t) have been plotted using MATLAB on a 4 by 4 grid with timescale from -1 to 1 μsec.

Step-by-step explanation:

The MATLAB code was utilized to generate plots for the given signals a(t), b(t), c(t), and d(t) on a 4 by 4 grid using the subplot function. The timescale from -1 to 1 μsec was set for each plot to accurately depict the signals' behavior.

Each subplot, denoted as a(t), b(t), c(t), and d(t), represents different waveforms based on the provided mathematical expressions. The signals showcase variations in frequency and phase due to the additional cosine functions and different multiples of the fundamental frequency.

Through MATLAB's visualization capabilities, these signals are graphically represented in a clear and organized manner, aiding in the comprehension of their temporal characteristics and variations across the given timescale.
