DIY Homemade Signal Generator with Pulse Width Modulation
Construct a signal generator using readily available components. It should produce a square wave with variable frequency and adjustable pulse width. This device can be utilized for various applications, including DC motor speed regulation, dimming of lamps or LEDs, transformer...
10 Hz to 10 Khz Voltage Controlled Oscillator
A voltage-controlled oscillator (VCO) is an oscillator whose frequency is regulated by a voltage signal. The VCO discussed here can generate both triangular and square wave outputs. The control voltage can be adjusted between 5 mV and 5 V, resulting...
Precision Oscillator With 20ns Switching
A precision oscillator can be constructed using a quartz crystal; however, with appropriate component selection, it is also possible to build one using an RC (resistor and capacitor) circuit.
An RC oscillator generates an oscillating signal through the use of resistors...
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....
Two-function-signal-generator
This circuit allows for continuous variation of the frequencies of the triangle and square waves produced, covering a full decade. When the resistance of RS is approximately equal to R3, the amplitudes of the two waveforms will be equal (A_SQUARE...
tune coil
Tuning a system is typically a challenging task. The user must power the system, observe the spark length, shut it down, adjust the primary tap, restart, and repeat this process until the spark length is optimized. However, using a tuning...
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,...
Precision-full-wave-rectifier
This circuit provides accurate full-wave rectification. The output impedance is low for both input polarities, and the errors are small at all signal levels. It is important to note that the output will not sink heavy currents, except for a...
300kHz signal generator circuit
This circuit is designed for a 300 kHz signal generator. It includes components such as VT1, T1, VD4, and other associated elements. The voltage-controlled oscillator (VCO) employs an LC-tuned collector, with VT1 functioning as the oscillating transistor, varactor diode VD4,...
