Comparison between different modulation schemes in terms of frame rate/display time for DMD with refresh rate of 32 kHz.

Modulation\specs	Frame rate	Minimum display time
Binary (1-bit)	$32\text{kHz}$	$31.25\mathrm{\mu }\text{s}$
Time (8-bit)	$125\text{Hz}=\frac{32\text{kHz}}{2^8}$	$8\text{ms}=31.25\mathrm{\mu }\text{s}\times 2^8$
Time (4-bit)	$2\text{kHz}=\frac{32\text{kHz}}{2^4}$	$0.5\text{ms}=31.25\mathrm{\mu }\text{s}\times 2^4$
Amplitude (8-bit)	$4\text{kHz}=\frac{32\text{kHz}}{8}$	$250\mathrm{\mu }\text{s}=31.25\mathrm{\mu }\text{s}\times 8$
Amplitude (4-bit)	$8\text{kHz}=\frac{32\text{kHz}}{4}$	$125\mathrm{\mu }\text{s}=31.25\mathrm{\mu }\text{s}\times 4$
