Wave Amplitude

Altair Forum User

Hey guys, 

 

How can I have a -1:1 amplitude in the square wave? I've tried to combine two square waves (see attached file). One positive and one negative with a 1 second delay, but unfortunately de Time Delay option makes no modification on the signal, hence the two signals are cancelling each other.

 

Thanks for your help.

Hi Joseph,

         You did correct only. But, check the frequency of both square waves are 1 Hz and delay of First square wave is Zero and Second square wave is 1 sec. The square wave block always produce a wave with 50% duty cycle. It means that, both the waveforms are on for 0.5 sec and off for 0.5 sec. If you want a square wave amplitude range from 1 to -1, then you need to change the delay to 0.5 sec instead of 1 sec. The above approach is not a right one, because, at starting the square wave looks like an amplitude of 0 to 1. Please check the below figure for reference (Observe 0 to 1 sec in plot).

 

 

            Instead of adding two square waves with a delay of 50% Frequency. Use the below method. In this method, I used a sinusoid block whose output is connected to a relay (available in Non-Linear Blocks) and connect its output to Plot block. Please check this below figure for your reference, by eliminating the above problem.
