Standard Periodic Waveforms

square, triangle and sawtooth by adding sinusoids.

Table 1: Standard Waveforms Synthesized by Adding Sinusoids

Type	Harmonics	Amplitude	Phase (cos)	Phase (sin)
square	$n = [1, 3, 5, ..., N]$	$1/n$	$-\pi/2$	0
triangle	$n = [1, 3, 5, ..., N]$	$1/n^2$	0	$\pi/2$
sawtooth	$n = [1, 2, 3, ..., N]$	$1/n$	$-\pi/2$	0
