data T rate amplitude body

A signal value 0.5 at global amplitude 1 and signal value 1 at global amplitude 0.5 shall represent the same signal. Thus it is unsafe to observe the amplitude.

Cyclic nature such as needed for Fourier transform must be expressend in the body. It would be nice to use the data type for waveforms, too, but for waveforms the rate parameter makes no sense.
