CMOS (Complementary Metal-Oxide-Semiconductor) and TTL (Transistor-Transistor Logic) are two of the most widely used digital logic families in electronic circuits. While both have their own strengths and weaknesses, CMOS technology has several distinct advantages over TTL that make it a preferred choice in many applications. In this comprehensive guide, we will explore the key advantages … Read more
Low Pass Filters (LPFs) are a fundamental concept in electronics and control systems, and they operate on the principle of reactive components. LPFs are designed to allow low-frequency signals to pass through while blocking high-frequency signals. This is achieved by using reactive components such as capacitors and inductors, which have a phase shift between the … Read more

A signal in communication systems refers to any type of information that is transmitted from one point to another, including data, voice, video, or any other type of information that needs to be communicated. Signals can be analog or digital and can be transmitted over a variety of different mediums, including wired and wireless channels. … Read more
The Nyquist-Shannon sampling theorem is the fundamental principle that determines when signals should be sampled at a higher rate in digital systems. This theorem states that a signal must be sampled at a rate that is at least twice the highest frequency component of the signal (fmax) to avoid aliasing, which can lead to distorted … Read more
The steepness of the roll-off in a low-pass filter (LPF) is a crucial parameter that determines the filter’s ability to separate the desired signal from unwanted high-frequency components. As the order of the filter increases, the roll-off becomes steeper, providing better attenuation of the stopband frequencies. However, there are practical limits to how steep the … Read more
