If you put a divide by 1.5 circuit in the feedback loop of a PLL, you can
get multiplication by 1.5 so 100*1.5=150, and so on with the others.

Also, if you use a phase shift type of delay, (which isn't very practical),
you'll get a frequency dependent amount of delay.

I'm not sure those halfway numbers are correct (150,250)
