Hi

how can i generate the signal sine wave with a variable frerquency, i need to use the function matlab with Clock for the time. ??

Thnks

Not sure how you'd like to implement clock(), though.

If there is no constrain, you could multiple the Clock with 2*pi*f, where f is your frequency and then feed it to an "Interpreted MATLAB Fcn" block where you specify it as "sin" or "sin(u)". You could implement "f" as a constant, or a parameter or an Inport.

but i need to take the frequence as an random variable between 50 and 250 Hz ??

then multiply the Clock with 2*pi and the Random Number block.
