Hi,
As per the problem statement, Please find the solution below with in-lined comments:
Note: included zoom feature , As no mentioned like specific zoom requirements , basic zoom on implemented on both plots
Program1: Describes the Plot for Time Vs Modulation Signal as follows:
ModulationSignalPlot.m
% Plot for time Vs 2-bit modulation signal as follows
% no of bits % Finding the Modulating signal as follows %Plot Time Vs Modulating signal xlabel('Time (sec)'); |
Please find the output below:
Program2: Plot from Time Vs Carrier Signal as follows:
CarrierSignalPlot.m
% Plot Time Vs Carrier Signal as follows % Given frequency in MHz so converting into

Please find the output below:
Please find the ASK_Modulating_signal.m for reference:
function [mt] = ASK_Modulating_signal(n,t) Amp_level = 0:1/(n-1):1; mt = zeros(1,length(t)); lm = round(10000*rand(1, length(Amp_level))); Idmx = round(length(t)*rand(1, length(Amp_level))); for i=1:length(lm) if Idmx(i) < lm(i) lm(i) = round(Idmx(i)/3); end if Idmx(i)+lm(i)/2 > length(t) mt(1,Idmx(i)-round(lm(i)/2):length(t)) = Amp_level(i); else mt(1,Idmx(i)-round(lm(i)/2):Idmx(i)+round(lm(i)/2)) = Amp_level(i); end end end |
