PLL FM Demodulator
A Phase Locked Loop (PLL) can be utilized to create a Frequency Modulation (FM) demodulator. The PLL circuit tracks the input frequency by adjusting the voltage input of a Voltage-Controlled Oscillator (VCO).
The Phase Locked Loop (PLL) is a critical component...
5W RF power amplifier
Numbered components are designated for PC-board layout purposes. C5 and C8 are disc ceramic capacitors. C6 and C7 are tantalum or electrolytic capacitors. R1, R2, and R3 are 1/4 W carbon composition resistors. Silver-mica capacitors may be substituted for polystyrene...
NE568 NE568A;SA568A 150MHz Phase-locked Loop
NJM2268 is a dual video 6dB amplifier designed for S-VHS VCRs, high-bandwidth VCRs, and similar applications. One channel features a clamp function that stabilizes the DC level of the video signal, while the other channel operates as a bias type....
Icom IC-751 RAM reprogramming
Everything appeared to be functioning normally. The half-duplex operation and pedal control in telegraphic mode allowed the operator to transmit while listening during pauses, seamlessly switching to the standard mode by simply pressing the pedal at the right moment. Previously,...
Farnsworth Model GT-051 Bakelite Radio (1948)
"Black Beauty" is a nickname for a classy Bakelite radio set. It features a dramatic, asymmetrical design with deep wraparound louvers and a bullet-like profile, exemplifying 1940s Streamline design. The radio is undergoing restoration of its electronics and cabinet. Originally,...
Wireless Color Sensor
Close to human perception and stable color sensing is a pervasive challenge encountered in various disciplines, such as machine vision for classification and recognition, as well as in intelligent systems like smart illumination systems in home or workplace environments. In...
Radio harmonic detection circuit
The demodulation and detection circuit is a radio AM intermediate frequency (IF) signal amplifier that performs two-stage detection using diode Dr. It extracts the audio signal from the IF carrier detection and subsequently sends it to the power amplifier stage....
Old-Time Radio
This circuit was utilized in the early days of radio for signal reception. It can employ nearly any battery-operated triode, such as a type 30. The "A" battery provides 3 V, R2 is a 100-ohm rheostat, and the coils are...
