Digital Sine Wave Oscillator
If found myself in need of a 1 KHz signal source for an experiments. My function/sweep generator was needed as a pulse generator for the same experiment, so I went though my junk box, looking for circuits from long ago...
Sine wave oscillator low frequency-constant amplitude
In a sine wave oscillator circuit, a thermistor and an incandescent lamp are often utilized to stabilize the output of the circuit at a fixed value. The resistance of...
The sine wave oscillator circuit is designed to generate a continuous sine...
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...
High-performance quadrature sine wave oscillator
Many RC oscillators utilize an advanced circuit in the phase shift unit. This configuration employs a voltage feedback amplifier, which experiences a significant decline in gain at higher frequencies, leading to the cessation of oscillation before achieving the desired frequency....
Basic-function-generator
This function generator utilizes a CA3260 BiMOS operational amplifier to perform both integrator and switching functions. A 620-pF capacitor and a 2-kΩ resistor are employed to shape the feedback square wave, minimizing spikes. The device covers the full audio spectrum...
Building a Sweep Generator for BK 4011
A teardown of a BK Precision 4011 5MHz function generator revealed that, like most basic function generators from earlier times, the BK 4011 does not include frequency sweep as a standard option. However, it does feature a VCG (Voltage Controlled...
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...
Function Generator Sine / Triangle / Square / Saw ( PIC16F870 )
After the recent demise of our multifunction signal generator, we decided to make one of our own. The circuit uses a PIC16F870 (about $3), an R/2R resistor ladder network (for a real fast and cheap D/A), and a few other...
