Parameters of the converter and transfer function for each case.

Case	Frequency (kHz)	Z domain transfer function	Remarks
1	20		Poles inside the unit circle, zeros lie outside the unit circle, up-down and down-up glitches, multiple zero crossings
2	21		Poles and zeros lie outside the unit circle, up-down glitches, multiple zero crossing
3	22		Poles and zeros lie inside the unit circle, up-down glitches, multiple zero crossings
4	23		Poles outside and zeros inside, up-down glitches, single zero crossing
5	24		Poles outside and zeros inside, unit circle, up-down glitches
