Testing Signals
Sinusoidal signals
They have double simetry, one in the time and the other one respecting the middle point of the signal. If a sinusoidal signal is delayed 90° you will know you have a cosinusoidal signal.
-
Triangle signal
This one is non-sinusoidal waveform named for its triangular shape. It is a continuous real function. The speeds of growth and decrease are called slopes. If both slopes are equal, the sign will be called triangular: otherwise it will be called sawtooth.
