Analog Equaliser
The time constant of R1C1 determines the low cutoff frequency, while the time constant of R2C2 determines the high cutoff frequency. The pass-band gain, Avpass = R2/R1. For a high-pass filter, Za must be capacitors and Zb resistors. By substituting...
1.8kHz signal generator circuit
The circuit depicted in the figure allows for the selection of optimal operating conditions and a suitable allocation of the temperature coefficient for the resonant circuit components. The resonance occurs at both ends of the circuit. Additionally, the exchange regulator...
Audio Oscillator
A low distortion audio frequency sine wave can be generated by passing the output of a simple square wave oscillator through a sharp cutoff low-pass filter to attenuate the odd harmonic components. The output level of the sine wave is...
Triangle-to-sine converters
The conversion of triangle waveforms to sinusoidal waveforms is typically achieved using diode-resistor shaping networks, which effectively reconstruct the sine wave segment by segment. Two simpler and more cost-effective methods can be employed to shape the triangle waveform of the...
Linear ac analog coupler
The coupler is biased in the linear region using a 10 mA DC bias on the infrared emitting diode (IRED) and a voltage divider connected to the base of the phototransistor. This configuration allows the photodiode current to flow from...
Signal Generator Circuit

OP AMP SINE WAVE GENERATOR CIRCUIT
An operational amplifier-based sine wave generator circuit, commonly known as a Wien bridge oscillator, is recognized for its simplicity and stability. The Wien bridge oscillator connects the Wien bridge circuit between the amplifier's input and output terminals. The bridge features...
Square wave-to-triangle converter
This fixed-frequency triangular waveform generator, driven by a TTL square wave, produces triangular waveforms with a peak-to-peak voltage of typically 16 V at frequencies reaching several MHz. The design utilizes a single AND open collector gate or an open collector...
