Sine wave converter circuit
The circuit serves as a signal source for calibration level meters or sensor-driven differential transformers. The oscillation frequency is determined by the 74HC04, producing a frequency of 1 kHz through resistor R. The supply voltage of the circuit changes in...
sine to square triangle wave
If a triangle wave signal or a square wave is required but only a sine wave generator is available, this converter can be utilized to simplify the process. The circuit consists of two integrated circuits (ICs): an LM13700 and a...
Wien oscillator
Construct a sine wave generator using the TL082 operational amplifier and a 9V power supply. However, the output is producing a distorted waveform rather than a clean sine wave. There is a need for a list of components suitable for...
Rectangular/Triangular Waveform Converter
Many function generators utilize a rectangular waveform generator that comprises a Schmitt trigger and an integrator. The triangular signal generated by the integrator is subsequently transformed into a sinusoidal signal using a diode network. The converter described here operates inversely,...
Adjustable Sine/Square Wave Oscillator
The following diagram illustrates the schematic of a simple, easily tuned adjustable sine and square wave oscillator. This circuit generates sine and square wave signals at frequencies ranging from below 20 Hz to above 20 kHz. The advantage of this...
Self Powered Sine Wave to Square Converter
This circuit utilizes a single active component, the 4069 IC, to convert sine waves into square waves without requiring an external power source. It is designed for testing audio instruments.
The circuit leverages the characteristics of the 4069 IC, which is...
Crescendo ampilifier elektor1982
The Elector Crescendo was the first DIY amplifier that was not a kit. The design was sourced from the Elector magazines available at a local library.
The Elector Crescendo is an innovative audio amplifier designed for DIY enthusiasts. It features a...
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...
AudioWave 2.0
With AudioWave 2.0 your soundcard becomes a comfortable LF-signal-generator, which produces signals from 1Hz to 20 kHz with a resolution of 1 Hz. Phase shift between left and right channel is adjustable from 180° to +180° and an attenuator can...
