Hi people,
I want to generate a sinusoid with asymmetric amplitude. The positive amplitude must be 1 and the negative amplitude must be 0.5.
How can I do It?
thanks

t=0:0.01:10;
f=sin(t);
f(f<0)=f(f<0)/2;
plot(t,f)

PosAmp = 1.0;
NegAmp = 0.5;
sinus = PosAmp .* linspace(0,50*pi,500);
sinus(sinus<0) = sinus(sinus<0) .* (NegAmp ./ PosAmp);
