Problem 1
Pick a CT periodic signal that was posted on Rhea as part of homework 1, and create two DT signals, one periodic and one non-periodic, by sampling at different frequencies.
Using Eric Zarowny's function of y(0)=sin(t) I graphed the function using a periodic (.1) and a non-periodic (2) sampling rate.
This graph was generated with the following code
clear
clc
ratt=(0:.1:6*pi);
nonratt=(0:2:6*pi);
rational=sin(ratt);
nonrational=sin(nonratt);
hold on
plot(ratt,rational,'b')
plot(nonratt,nonrational,'r')
legend('Periodic Sampling', 'Non-Periodic Sampling')
hold off
Problem 2
Using Xujun Huang's function $ e^t $ I was able to create a periodic signal.
The matlab code is as follows:
clear clc t=(0:1:6); y=exp(t); newy=[y,y,y]; fullt=1:1:length(newy); plot(fullt,newy,'b')
