Synchronize & Compare Two Analog Signals
Synchronize & Compare Two Analog Signals
(OP)
Hello,
I am looking for a circuit design that will allow me to synchronize two incoming analog signals (one reference and one unknown) which would allow me to compare them to see if they are similar or different.
I am not to familiar with appropriate terms and phrases like, "phase lock loop"....etc. This is sort of hindering my search results.
The specifications for the circuit are not really important right now seeing as I am looking for the function first. However, as a reference, I will use +/-5V AC signals with no greater than 100kHz frequencies.
Thank you

We want to compare these signals to pre-recorded signals that pose as a baseline/reference.
RE: Synchronize & Compare Two Analog Signals
It's going to be a much different problem if you're comparing two sine waves than if you're comparing two arbitrary waveforms.
RE: Synchronize & Compare Two Analog Signals
In general, the waveforms will be DC with some transients (~450us).

What exactly are you trying to measure... feeding us info piecemeal isn't going to get you a useful answer and will more than likely just annoy everyone until we give up.

Amateur EME or professional something-or-other?

How similar?
How different?
