We are familiar with the missing pulse detector circuit, which detects the occurrence of a missing pulse in a pulse train where the pulses are of equal duration. But this circuit detects the long ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are ... s also pretty easy to understand: the pulse counting detector. As [Allan (W2AEW ...

He’s built a finger-mounted pulse detector using a few simple components and an Arduino. This circuit uses a method known as photoplethysmography. As blood is pumped through your body ...

An impulse detector circuit observes input pulses from an external sensor/source and converts into a processable output signal. Described here is a microcontroller-compatible event detector circuit ...

Gentec-EO’s QE12HR and QE25HR pulse energy detectors are designed for use with Q-switched lasers and pulsed laser diodes. These laser energy detectors feature an improved temporal response to ...
