Sinusoidal signal wave plotting

a script creating a sine wave with 3 units amplitude and length of 50?

% Generation of a sinusoidal sequence n = 0:40; f = 0.1; phase = 0; A = 1.5; arg = 2*pi*f*n - phase; x = A*cos(arg); clf; % Clear old graph stem(n,x); % Plot the generated sequence axis([0 40 -2 2]); grid; title(’Sinusoidal Sequence’); xlabel(’Time index n’); ylabel(’Amplitude’);

One of these will solve your issue:

• sind or sin
• MATLAB Onramp
• Using search tool to find an answer to your question

@Steph surry To get a sinusoidal signal, use a sutable frequency for input signal.

n = 0:0.5:50; 
f = 5; % use a suitable frequency 
phase = 0; A = 3;
arg = 2*pi*f*n - phase; 
x = A*cosd(arg); 
% Clear old graph 
stem(n,x); % Plot the generated sequence 
axis([0 40 -3 3]); grid; title('Sinusoidal Sequence'); xlabel('Time index n'); ylabel('Amplitude');
