When I looked into a making a cheapish broad band receiver, these lost out to the chip sets used for SDR. For an extra couple of bucks I got a USB dongle that tuned 26-1750Mhz versus a bare chip ...

// Finite impulse response, Infinite impulse repsonse, filter parameters // Noise reduction techniques like noise gating or adaptice noise cancelling // Use signal processing libraries // ...

This project implements a control system for a VHF (Very High Frequency) Communications Transceiver, utilizing an Arduino board to interface with a 4x4 keypad and a 7-segment LED display. The system ...

The authors investigate the mutual compatibility of the usual traffic announcement analog secondary broadcasting ARI (auto radio information) service and simultaneous digital secondary service, known ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

This paper describes the design aspect of VHF/UHF Receiver covering VHF to UHF band with excellent selectivity, sensitivity and wide dynamic range. The principle of operation of this receiver is based ...
