Hello, I need help generating a single cycle of a sinewave at a particular frequency and sampling rate. The following example generates multiple cycles and I am not sure how to get a single cycle.
fs = 512; % Sampling frequency (samples per second)
dt = 1/fs; % seconds per sample
StopTime = 0.25; % seconds
t = (0:dt:StopTime-dt)'; % seconds
F = 60; % Sine wave frequency (hertz)
data = sin(2*pi*F*t);
Thank you,

Could any one share matlab code for storing the signals data in 2 arrays of 64 elements

clc;
clear all;
close all;
L = 3; %Up-sampling factor
M = 2; %Down-sampling factor
n = 0:29;
x = sin(2*pi*0.43*n) + sin(2*pi*0.31*n);
y = resample(x,L,M);
subplot(2,1,1),stem(n,x(1:30));
xlabel('Time index n');
ylabel('Amplitude');
title('lnput Sequence');
m = 0:(30*L/M)-1;
subplot(2,1,2),stem(m,y(1:30*L/M));
axis([0 (30*L/M)-1 -2.2 2.21]);
xlabel('Time index n');
ylabel('Amplitude');
title('Output Sequence');

fs = 512; % Sampling frequency (samples per second)
dt = 1/fs; % seconds per sample
StopTime = 0.25; % seconds
t = (0:dt:StopTime)'; % seconds
F = 60; % Sine wave frequency (hertz)
data = sin(2*pi*F*t);
plot(t,data)
%%For one cycle get time period
T = 1/F ;
% time step for one time period
tt = 0:dt:T+dt ;
d = sin(2*pi*F*tt) ;
plot(tt,d) ;

Generate the following signals in MATLAB using subplot command such that the x-axis title contains your UET (2 Fig Roll No.) and y-axis title contains your APCOMS (4 Fig Roll No) while the title of the plot shows your Name and Batch No. (CLO-01, PLO-5) (25 Marks)
- Sinusoid
- Kronecker Delta
- Unit step signal
- Ramp
Complex Exponential

Demonstrate the designing of a circuit in MATLAB Simulink such that it represents the equation sin2 φ + cos2 φ = 1 where φ = UET (2 Fig Roll No.) the output should have an amplitude of 1 on the “scope”. Save the .mdl file and attach it in the online submission of this assignment. Also add its screenshot in the assignment.

Demonstrate the generation of a Saw Tooth wave from its Fourier Series in MATLAB such that the x-axis title contains your UET (2 Fig Roll No.) and y-axis title contains your APCOMS (4 Fig Roll No) while the title of the plot shows your Name and Batch No.

Find and Demonstrate the inverse Z-Transform of following. Here a and b are the two digits of your UET (2 Fig Roll No.) whereas c, d, e and f represent the 4-digits of your APCOMS (4 Fig Roll No).
