square
Generate a square wave with range [-1,1] and period 2*pi.
Syntax
s = square(t)
s = square(t, duty)
Inputs
- t
- The times at which to generate the signal.
- duty
- The percentage of time for which the wave is at +1. (default: 50)
Outputs
- s
- The square wave.
Example
Plot five periods of a square wave.
t = [0:0.01:2]*(2*pi);
s = square(t);
plot (t, s);
xlabel('time');
ylabel('amplitude');
