Now we assume the tacho signal. The tacho pulse we put to the T0 position.
T0
Corresponding time signal with tacho pulses is on the following picture.
Now we begin to assume the phase shift (marked as φ) of time signal vs. tacho signal. The signal formula
changes to y=cos(ωt + φ). The previous picture corresponds with φ=0°. And this value is displayed on the
instrument screen. When the tacho pulses are in the maximum time signal positions, then phase value is equal
to zero.
Now assume the φ=45°. We use the degrees unit to make it simple for all readers. The radians have to be used
in exact math formula.
