Qrp Sidetone Generator Code Practice Oscillator Circuit
For use with low-power transmitters that require a positive keying voltage. The transistors Q1, Q2, and Q3 are configured as a switching amplifier. When the key is pressed, the collector of Q3 is pulled to ground, which activates Q5 and...
Mini Audio Signal Generator
A small audio test generator is highly effective for quickly tracing signals through audio equipment. Its primary function emphasizes speed over precision. Typically, a single sine-wave signal of approximately 1 kHz suffices, and distortion levels are not critically important. However,...
Micropower Clock
Ceramic resonators are suitable for low-power, low-frequency clock sources, despite their 30-ppm temperature coefficient. However, they exhibit troublesome spurious-resonance modes. This circuit effectively rejects all but the fundamental mode of the resonator. The clock circuit operates within a temperature range...
RF Signal Generator
This signal generator is designed for the realignment of radio receivers. It is an economical and straightforward unit, adequate for its intended application. However, the output is not a pure sine wave, which may limit its suitability for more precise...
Low Power Negative Car Power Supply
I have had a lot of queries about getting a low power negative supply in cars, to power Linkwitz transform circuits and the like. There is a switchmode converter, but I must admit that it is overkill for what most...
RF Signal Generator circuit
This signal generator is designed for the realignment of radio receivers. The unit is inexpensive and relatively simple but adequately serves its intended purpose. However, the output is not a pure sine wave, which may make it unsuitable for more...
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...
Signal Generators Circuits
Converting periodic waveforms to square waves is essential for extracting clock signals from data, creating waveform generators, and developing timing-pulse generators. A square-wave conversion circuit is more advantageous when the duty cycle of the square wave is variable and controllable....
