You may be already aware of the PWM and triangular wave generator. There are different kinds of waves such as sine waves, square waves, and triangle waves. Triangle waves are commonly found and used in audio production, and they are a common waveform source on synthesizers. On the other hand, pulse width modulation (PWM) is a method of changing the duration of a pulse … [Read more...] about PWM and Triangular Wave Generators | Circuit and Simulation

Amplifier Circuits Using Op-amp Inverting, Non-Inverting and MOSFET
You may already know that Amplifier circuits are two-port electronic circuits that receive electric power from a power supply and increase the amplitude of the signal at its output in regular terms. But do you know how to make amplifier circuits using Op-amp and MOSFET or how do they work? Inverting amplifiers are one of the most popular operational amplifier circuits that … [Read more...] about Amplifier Circuits Using Op-amp Inverting, Non-Inverting and MOSFET

Automatic Temperature Controlled Fan Circuit Using Thermistor
This is a simple automatic temperature-controlled fan circuit using an NTC thermistor. The main components of this temp control fan circuit are a negative temperature coefficient thermistor (NTC) which detects the temperature, a comparator which is used to compare the preset temperature value, and a relay circuit to drive the fan. The power supply … [Read more...] about Automatic Temperature Controlled Fan Circuit Using Thermistor
Binary Phase Shift Keying (BPSK) Modulation Using cd4016 With Simulated Output Waveform
In binary phase-shift keying (BPSK), the phase of a carrier is changed according to the digital pulses signal. BPSK modulator is a phase modulator. Here the transmitted signal is a sinusoid of fixed amplitude. It has one fixed phase when the data is at one level and when the data is at the other level, the phase is shifted by 180 degrees. The binary phase-shift keying method … [Read more...] about Binary Phase Shift Keying (BPSK) Modulation Using cd4016 With Simulated Output Waveform
