Duty cycle

As explained in Learn Haskell by Example

A duty cycle is the fraction of each period during which a pulse signal remains in its high or low state.

A duty cycle is the fraction of each period that a pulse signal remains high or low. It changes the sound characteristics of a pulse wave. section 10.1.2

A square wave

A square wave has a 50% duty cycle: the signal stays low for the same amount of time that it stays high. section 10.1.2

Use duty cycle when designing pulse-based audio:

  • Treat 50% as the balanced square-wave case. section 10.1.2
  • Experiment with adjustable values to create a generic pulse waveform and explore changing sound characteristics. section 10.1.2

How Learn Haskell by Example covers it

How deep it goes
Defines the 50% case and assigns adjustable pulse-wave implementation as an exercise without supplying its completed implementation.
Examples
Uses a square wave with equal high and low durations and an exercise requesting a generic adjustable pulse waveform.
What you can do after
Practice/perform implementing a generic pulse waveform with an adjustable duty cycle.
How it connects
Connects duty cycle with pulse waves, square waves, waveforms, oscillators, signals, frequency, and musical sound.
