Questions tagged [square]
A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values. The square wave is a special case of a pulse wave which allows arbitrary durations at minimum and maximum. The ratio of the high period to the total period of a pulse wave is called the duty cycle. A true square wave has a 50% duty cycle (equal high and low periods).

What type of input is required by a gate driver? The data sheet says 50 A
I'd like to drive a TI UC3708N gate driver from a handheld AWG square wave that varies between 0V and 2.5V. According to the data sheet, anything above 2V should be treated as high:
However, I'm not ...
