PWM (Pulse Width Modulation) can be easily generated in MATLAB using simple MATLAB functions. We have already discussed PWM generator circuit using 741 Op-amp in previous posts. In PWM, the width of the pulses is varied according to the amplitude of the AF message signal. PWM is basically an analog pulse modulation technique. It does modulation of the duty cycle of the … [Read more...] about Code for Pwm (Pulse Width Modulation) Generation in Matlab

## Triangular Wave Generator Using Op Amp 741, Working and Simulated Output Waveform

An operational amplifier-based triangular wave generator using op-amp 741 is a simple circuit that is widely used in function generators. A triangular wave is the output of an integrator if the input to it is a square wave. It means that a triangular wave generator can be formed by simply cascading an integrator and a square wave generator, as illustrated in the figure. This … [Read more...] about Triangular Wave Generator Using Op Amp 741, Working and Simulated Output Waveform

## Full Wave Bridge Rectifier Circuit With Working Explanation

A rectifier is an electronic circuit that can convert the bipolar direction of the voltage into unipolar without changing its amplitude or frequency, which means AC voltage to DC voltage. Anyone can implement the circuit simply using a capacitor-diode combination. The unique property of diodes is they permit the current to flow in a single direction, this circuit … [Read more...] about Full Wave Bridge Rectifier Circuit With Working Explanation
