Can I just specify a variable and use this in the Sine Wave block to determine what the signal output is to be? WebIn theory a square wave has an instantaneous rise and fall. But it has a dwell time based on the frequency. Lets take a 1 hz square wave. The signal goes from zero to 100% [1] in an instant. Then will remain at 1 for 1/2 of the wave length or 500ms. Then it goes negative to -1 and remains there for 500ms.
