detector

Hello there! I am new to electronics, and I am trying to understand how this circuit works. Before it are 3 stages of Active Bandpass Amps. The whole circuit is trying to extract some AM signal from an antenna. I have already found how the Bandpass worked in the circuit, but I can't find...

We want to make a gold detector that can detect a depth of 5 meters What modules and sensors do you suggest to do this with high accuracy?

Hello all, I was wondering if you could help me identify a part (actually 2 parts) from a rotary encoder. It's a nice, heavy duty dual concentric switch from an old piece of avionics. I'm trying to find out more about its optical components . It has 2 emitters and 2 detectors on each deck...

The basic problem were trying to solve is certain secondary device's cables gets left unplugged and we need a way to detect a cable that is plugged into my device,and check if that cable is actually plugged into a secondary device and not hanging around unplugged. I have a cable with 5 pins on...

Hello, everyone! I have a problem with approaching a university project, which aim is to detect the phase drifts (difference, deviation) between a mains supply voltage and either an internal reference and externally input reference signal. The system should be micro-controller based (MSP430)...
