Hello,
I have to model the damped sinusoidal wave: y = A*sin(w*t-phi).*(exp(-B*t) where:
A=0.2 B=1000 f_s=2000 t = [0:.00001:0.005]; w=2*pi*f_s phi= 1.0472
I know how to do it in Matlab but not in Simulink, as I don't know which blocks I have to use to add the exponential part to the function.
Can someone help? ( a picture of the model would be so appropriate...)
Many thanks,
Lluís

Hello Lluís,
You can get the damped sine wave in Simulink with this approach. In the "Sine Wave" block, you can give the frequency, amplitude and phase of the signal.
