This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...
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 ...
In ring oscillator-based PLLs, the VCO is typically implemented using a ring oscillator with a class-C configuration. To improve stability, an Amplitude Adjustment Circuit (AAC) is used to stabilize ...
For electronic equipment with sensitivity to a narrowband of frequencies, SSC helps to generate less interference. Figure 3 demonstrates the clock's spectrum before and after spreading. After SSC, the ...
