Hi i am currently working on a project which deals with lock in amplification system, all this time i have been working on analogue electronics but now my supervisor wants me to convert the system into digital at the last minute
the main part of my project is the phase sensitive detection stage where i multiply a noisy signal with its reference signal to produce the output .... but now i guess i have to provide the a/d stage before it .... can anyone please give a short brief of how to do it ? the only thing i can think of is passing both the signals through a adc chip and then multiplying signals (not sure tho how to multiply them)
I would greatly appreciate the help
