Voltage-controlled-attenuator
This typical circuit utilizes an external operational amplifier for improved performance, along with an exponential converter to achieve a control characteristic of -6 dB per volt. Trim networks are incorporated to eliminate distortion and offset, as well as to finely...
How to amplify a square wave cheaply
A piezo disk is being driven at a frequency of 100 Hz or lower, with the output from the signal generator limited to 10 V. The goal is to amplify this output to 50 or even 100 Volts.
To achieve the...
Signal Generator circuit
The output level was set to 3.8V peak to peak. The initial objective was to compare several different operational amplifiers (op-amps) before further optimizing the circuit. The op-amps evaluated were the TL072, LM4562, and OPA2134. The distortion spectra are presented...
SQUARE WAVE GENERATOR EMBEDDED C
A common requirement across various applications is a continuous signal source that produces a regular and definable waveform. Among these waveforms, the square wave is particularly significant. The circuit described utilizes a comparator featuring both positive and negative feedback to...
Square Wave Oscillator
This circuit utilizes the Op-Amp LM301 to generate a simple square wave. The LM301 operates with a power supply range of 3 V to 36 V and can handle a maximum frequency of 325 kHz. The oscillation frequency is determined...
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...
Variable Square Wave Generator Circuit
This simple square-wave generator produces a variable frequency output ranging from 2800 Hz to 80 kHz, as indicated by the specified values. The frequency can be adjusted using potentiometer R1.
The square-wave generator circuit typically employs a combination of resistors, capacitors,...
Simple square wave generator
Square wave generators are typically based on symmetrical multivibrators using bipolar transistors of the same structure, along with two frequency-determining networks. However, a simpler oscillator can be constructed with two transistors of different structures (refer to figure 1) utilizing only...
The Multi-purpose signal generator circuit
The multi-purpose signal generator circuit consists of integrated circuit oscillators and frequency dividers. It generates square waves ranging from high frequencies to sub-audio frequencies and also produces a frequency standard in the VHF range. The alternative oscillator section feeds the...
