fm receiver with tba120 ca3089 ca3189

Ralph Stirling, KC3F, and another engineer developed the first generation of a digital signal processing (DSP) system using the Texas Instruments C5X DSK starter kit. The second generation represents a significant advancement, utilizing the more appropriate Motorola DSP56002EVM evaluation...

This circuit generates audio musical notes that can be heard from a distance of up to 10 meters. The circuit is divided into two parts: an infrared (IR) music transmitter and a receiver. The circuit operates on the principle of...

The circuit consists of transistors VT1 through VT7 and other components. Due to the weak signal received from the transmitter, the circuit employs a multi-stage amplifier to enhance the output. This output generates a square wave pulse signal to...

GENERAL DESCRIPTION The TDA7000 is a monolithic integrated circuit designed for mono FM portable radios or receivers, emphasizing minimal peripheral components to achieve compact dimensions and reduced costs. This integrated circuit features a Frequency-Locked-Loop (FLL) system with an intermediate...

An Icom PCR-1000 is utilized for listening to various MF, HF, and VHF radio stations. There is a minor inconvenience related to the antennas. The K9AY antenna performs well from 500 KHz to approximately 25 MHz, while the discone...

This project is a PLL synthesized FM radio which can decode DTMF. The receiving frequency can be set by the PLL circuit from 80-140MHz. The receiver is VERY stable, high sensitivity and easy to build and tune. The FM...
