The circuit presented here in this project generates two different types of wave forms using two OP-AMP chips LM741. It generates square wave and triangular wave. These waveforms can be applied as input to any other circuit to test their operation. Like square wave can be applied to any digital device as pulse input and triangular wave can be given to sweep frequency generator that will generate different frequencies (frequency sweep from min to max) as positive (or negative) ramp of triangular wave is applied.
How to Make Waveform of an IC by Only Choosing Resistors and Capacitors
An electronic circuit used to generate a continuous output signal usually in the form of a sinusoid at some predetermined frequency or wavelength set by the resonant components of the circuit.Wave is a signal that cannot be made by any simple device. It requires a capacitor and resistor combination that helps in the charging and discharging of the capacitor and makes that type of wave.There is a device called 8038 which generate any type of the waves.The 8038 waveform generator was an Integrated circuit by Intersil designed to generate accuracy sine, square & triangular waveforms based on bipolar monolithic technology involving Schottky barrier diodes. Triangular waves were produced by charging and discharging a capacitor with constant currents.
