Switching the output between signals

I have tw sine waves with different amplitude and stop time is 0.08,i used 2 sine wave blocks a switch with threshold of 0.04,and a clock..

Now i get output with half each waves,now i want to switch signals after each 0.02s

please assist

What is sample time of your model ?

[Pat]

Sampletime is 0

Answer 1

Multiply your sine waves with a pulse, which is 1 when the multiplied sine wave is supposed to be active, 0 otherwise. I think the pulse generator or repeating sequence blocks will be adequate.

Now add those two signals (the sine wave times pulse) using a SUM block. Voila.

Jonathan i dont know what uyou means by Multiply your sine waves with a pulse,

what does pulse indicate

[Jonathan Epperl]

Sorry, I misspoke, what I meant was a pulse train.

This here is a pulse

This is a pulse train:

I tried but it doesnot switch signals,fore ex my signals must switch after each 0.02s
