- 2011, Brian Cox & Jeff Forshaw, The Quantum Universe, Allen Lane 2011, p. 96:
  This is very clear for the standing waves on a guitar string: the fundamental has a wavelength of twice the length of the string, and the next longest allowed wavelength is equal to the length of the string. There is no standing wave with a wavelength between these two and so we can say that the allowed wavelengths on a guitar string are quantized.

quantize +? -er

quantizer (plural quantizers)

An electronic device that samples a varying quantity (e.g. a waveform) and generates a digital response
