Square wave

float uz_wavegen_square(float amplitude, float frequency_Hz, float duty_cycle)

Returns one sample of a square wave.

Parameters
  • amplitude – Amplitude for the square wave

  • frequency_Hz – Frequency for the square wave in Hz. Only positive values are permitted

  • duty_cycle – Duty Cycle for the square wave. Only values 0.0 <= DutyCycle <= 1.0 is permitted

Returns

Returns one sample for current system time
