The gain of an operational amplifier becomes infinitely high when in an open-loop configuration.

A logic-level shifter converts one voltage or logic level to another in an electronic circuit. Because of logic shifters, compatibility is developed between ICs that have dissimilar voltage requirements like CMOS and TTL. 

Digital circuitry is largely preferred in signal processing over analog because of its decreased sensitivity to fluctuations in various parameters as voltage, current, etc. and easy integration with computers.

Signal transmission from one point to another isn’t just about sending information between two channels.

If you grew up in the 80s or 90s, you probably remember the CRT televisions we had in our homes before LEDs took over.

The fact that analog signals provide continuous time values makes them ideal for real-time data monitoring. And while that’s an exceptional use of analog signal processing, we can’t ignore the fact that analog signals are more susceptible to errors, which makes their processing an extremely complex job.

Signal transmission over long distances often leads to a loss in the signal strength. To preserve the signal strength and combat this issue, designers often use amplifiers in combination with electronic circuits. While these amplifiers improve the signal strength, they often suffer from the effect of ‘noise.’

Signal processing has revolutionized the conventional methods of signal transmission. With the right equipment and technology, systems can now transmit signals over large geographical distances within a short duration.

Digital filters are a fundamental combination of digital signal processing. But before we talk about why digital signals are important, it’s essential to understand what caused designers to switch from the analog signal processing to digital signal processing.

Logic gates are the fundamental block of almost every electronic component. Based on Boolean Logic, these gates produce outputs corresponding to different input combinations.

Phase detectors are an integral part of modern day electronics and control systems. This article overviews the basic concepts of phase detectors. What are phase detectors? Phase detectors are circuits that generate a voltage signal proportional to the phase difference existing between two input signals. What is phase? Phase is the position of a point […]

Signal generators –we’ve heard about them a lot. They are used in many different fields of engineering. But what exactly are these devices and what do they do?

If you work with circuits and signals, you might have come across (or heard about) frequency multipliers; these devices are quite extensively used in electronics and system design.

Digital encoders are common electronic circuits used in almost all digital systems today. You can find them in pocket calculators, industrial control panels, navigation electronics, telecommunication devices, etc.

Phase-locked loops are discussed in a variety of contexts: demodulators, microcontrollers, serial communications, oscillator modules, etc.

Digital signal processing relies on many different components. One of these components are filters.
