Rf-genie
A variable oscillator operates in the frequency range of 3.2 to 22 MHz across two bands, enabling coverage from 80 meters to 15 meters, in addition to accommodating most crystal filter frequencies. Optional crystal oscillators at 455 kHz and 10.7...
Basic RF Oscillator circuit diagram
Experimenting with the size of the coil and the number of turns can influence the frequency and signal output of the oscillator. The signal can be received using a standard FM radio receiver. The input signal should be coupled via...
Half-duty-cycle-oscillator
The frequency of oscillation depends on the Rl/Cl time constant, allowing for frequency adjustment by varying Rl. This is a basic circuit.
The described circuit operates based on the relationship between resistance (Rl) and capacitance (Cl), which together form a time...
Sine-square-wave-oscillator
The circuit is designed to generate both sine and square wave outputs for frequencies ranging from below 20 Hz to above 20 kHz. The frequency of oscillation can be easily adjusted by modifying a single resistor, which is a significant...
Sine wave output V F converter
Most of the voltage-to-frequency (V/F) converters discussed in this chapter generate pulse or square-wave outputs. However, many applications, such as audio processing, filtering, or automatic equipment testing, necessitate a sine-wave output, which is produced by this particular circuit. The sine...
F007 stable sine wave oscillator circuit diagram
The stable sine wave oscillator circuit is designed to maintain consistent oscillation. The loop gain must be carefully managed; if the gain is excessive, waveform distortion occurs, while insufficient gain can lead to cessation of oscillation. This circuit employs two...
20Hz signal generator (phone-ringing) circuit diagram
The circuit described is a 20Hz signal generator suitable for telephone ringing systems, alarm systems, and various other electronic applications. It consists of a transformer (T) and two transistors (VT1 and VT2), forming a push-pull oscillator. The two transistors operate...
Wireless keyboard circuit
The circuit operates with VT3 and associated components arranged as a common-base capacitance feedback oscillation circuit. The oscillation frequency is set by capacitors C8, C9, and inductor L1. VT2 serves as a voltage amplification stage that reinjects the audio signal...
VHF/UHF TV Modulator
A simple oscillator generates a frequency in the VHF or UHF range. This oscillator is modulated with a video signal, and the resulting modulated carrier wave is transmitted to the TV set's aerial input through a cable. The final step...
