Math channel for duty cycle

Postby MDuBois » Sun Oct 27, 2013 4:55 am

Hello, I wonder whether or not anyone knows a formula for writing a math channel to display a graph of duty cycle? I would like to see a duty cycle percentage on a graph to know whether or not it cuts out at times, which would help me determine where a problem may lie. Thanks in advance, Marc DuBois

As a first hit you could use the integral function which would produce a trace for the area under the trace. For example a square wave with a 50% duty cycle would produce a triangular trace, which would drift down or up as the duty cycle changed.
