Superlinear FM (Frequency Modulator)
Designing various electronic circuit systems (synthesizer, modem, decoder, data converter, etc.) often requires a frequency modulator subsystem. An FM modulator is a crucial component in these systems.
An FM modulator is an electronic device that encodes information in a carrier wave...
Field circuit diagram of the needle
The antenna consists of approximately 20 cm of insulation made from strands, which are glued together inside a small plastic box. An RF current is processed through two diode rectifiers, and a 10k potentiometer is connected to the pin field....
Antenna ground loop Isolator
A ground loop in your AV system caused by antenna connection or TV cable is very common if you have your computer connected to the same system. This type of ground loop problem can be solved by using suitable isolation...
Four Foot Box Loop Antenna
Please find attached your copy of my four foot unamplified box loop. It will tune from 525 kHz to about 1710 kHz covering the entire Broadcast Band. The umbrella stand described in the article is the type you would use...
ZS100 Connection Signal
The following circuit illustrates a Noisy Regen Receiver Circuit Diagram. Features include its application in model remote-control systems and its operation as a 27-MHz superheterodyne receiver.
The Noisy Regen Receiver is a type of radio receiver that utilizes regenerative feedback to...
Receiver-Interface Circuit For Preamps Circuit
The purpose of the receiver/interface circuit is to pass RF to the receiver through capacitor C9, while adding DC power to the feedline through resistor R2 and RF choke L7.
The receiver/interface circuit is designed to facilitate the transmission of radio...
The R2 Single Sideband Direct Conversion Receiver
The old common-base audio preamp, which has a noise figure of 5 dB, is a clear candidate for improvement in noise performance. A common-emitter configuration with shunt feedback provides an input resistance of 50 ohms, which is preferred by the...
FM Radio Receiver Antenna Booster Circuit
This inexpensive FM radio receiver antenna booster utilizes the BF324 TO92 style PNP transistor in a grounded-base configuration. The circuit can be employed as a...
The FM radio receiver antenna booster circuit is designed to enhance the reception capabilities of FM...
TDA9887 IF-PLL demodulator with FM radio circuit
The integrated circuit (IC) is a multistandard vision and sound intermediate frequency (IF) phase-locked loop (PLL) demodulator that operates without the need for alignment. It supports multiple standards, including PAL, SECAM, and NTSC, and is capable of processing both positive...
