Hi,
I need some help for a project. I need to plot TWO cycles, frequency of 1khz sine wave with an amplitude of 5v. I'm using time as [0:2] but im not sure that's correct.
please help.

f0=1000 ; % sinusoid frequency in Hz
fs=50*f0; % sampling frequency
dt=1/fs; % sampling interval
duration=0.01 ; % duration = 0.01 seconds , which means this duration has 10 cycles
t=0:dt:duration-dt ; % time vector
sig=5*sin(2*pi*f0*t); % sinusoidal signal duration 0.01 seconds
plot(t(1:fs*2/f0),sig((1:fs*2/f0))) ; % plot of 2 cycles of the sinusoidal signal
grid

Hi , sorry for being late as I jsut saw the reply , run the code , accept the answer , thanks
%% generate and plot 2 sin(wt)
%% f= 40 Hz
f =40 ; % Sinusoid freuqncy
T=1/f; % Cycle durtation
fs=50*f; % Sampling frequency
dt=1/fs; % Sampling interval
t=0:dt:2*T-dt; % Time vector for 2 cycles
signal=2*sin(2*pi*f*t); % The required signal
plot(t,signal,'LineWidth',2) ; grid ; xlabel(' Time in Seconds ' ) ; ylabel ('Amplitude ' )
ylim([ -2.2 2.2])
