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…
The open-loop gain of an operational amplifier (op-amp) is considered infinite for ideal cases due to the input signal (differential or single) being slightly greater than zero. In practical terms, it is typically considered very high. Open-Loop Configuration in Op-Amp…
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…
A summing amplifier or an adder is used to sum two signal voltages. A voltage adder circuit is a simple circuit that enables you to add several signals together. It has a wide variety of applications in electronic circuits. For…
The LM339 is a quad-voltage comparator, which means it contains four separate comparators. The LM324 is a quad operational amplifier (op-amp) with four amplifiers. While it is not explicitly designed as a comparator, it can still be used for basic…
Op-amp and transistor are used according to your need. Though op-amp is better for amplifying gain, they are expensive. As the op-amp amplifier is made of different types of transistors. So, in many cases, you can use a transistor instead…
