sinewave generation:how generatea sine wave

i want to know how to generate a sine wave

Answer 1

[Daniel kiracofe]

t=0:0.001:1; freq = 10; signal = sin( freq * 2 * pi * t); plot(t, signal);

Answer 2

[MD Rasel Basunia]

% sinusoidal wave,x(t)=A*sin(2*pi*f*t); % set signal frequency f=10; %sampling frequency with oversampling %factor 50 fs=50*f; % sampling interval or period Ts=1/fs; %suppose you want to plot 6 cycle of sin %wave Number_of_cycle=6;

% time range for sin wave t=0:Ts:Number_of_cycle/f-Ts; % define sinusoidal %Amplitude A=2; x=A*sin(2*pi*f*t); plot(t,x,'k','linewidth', 2);grid on; xlabel('time');ylabel('Amplitude '); legend('sine wave');
