an array and a method directly accessible through the
Description
This function returns the amplitude coded on 16 bits, of a sine
waveform for a given step.
Input Parameters:
Step of the sine. Corresponds to the precision of the amplitude
calculation. Depends on the Sine Array used. Here, the array has
256 values (thus 256 steps) of amplitude for 180 degrees.
Output Parameters:
Amplitude of the sine waveform.
Sine Array with a resolution of 256 values for 180 degrees.
