DIY: Little Labs IBP

Post by CabreeToe » Tue Dec 16, 2003 11:44 am

Anyone got any info on how I could make something similar to the Little Labs IBP Jr. I'm mainly interested in builing a sweeping phase tool. I just can't afford that much.

An all-pass filter will give you a phase shift which can be varied, depending on the design. Here are some references:
