On a project I have recently been working on, I have come across a series of Phase Sensitive Demodulation (PSD) circuits. Although I understand the general principle of both switching-based PSD and multiplier-based PSD, I am struggling to find any concrete information about the whole concept of PSD, and I would like to at least have a better understanding on the topic.
Does anyone have any good information about PSD or know of any good resources on the subject? I've tried looking around the web and in some of the more respected books on circuit theory with little success.
Thanks.
Dave
