Crankshaft frequency

Hello,

For school we've been figuring if it would be possible to make a math channel that goes up and down when we play with the rpms of the engine.
I can't figure out how to do this and my teacher said it would be possible to create this kind of channel with a specified code.

For example: when stationary the revolutions of the crankshaft should be consistant at a certain rpm but if 1 cilinder would misfire there should be a decrease in the rpms.
When the rpm is decreased we would like to see the line dropping down as shown in the picture i've added.
(In the picture i've used the bottom dead center as a point where the line should go down since im using demo mode)

Does anyone know how to do this?

Thanks in advance!

Tools->MathChannels then create a math channel that is freq(A) and set the range to 0 to 3000 for the test signal

Thank you Martyn!

Maybe we thought to difficult and couldn't figure out why the line wasn't showing up properly.
