Magnitude or size of a signal voltage or current.  

Amplitude Modulation (AM) is the encoding of a carrier wave by variation of its amplitude in accordance with an input signal. Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. AM …

Analog PCB | Mad PCB Analog is a representation of an object that resembles the original. Analog devices monitor conditions, such as movement, temperature, and sound, and convert them into “analogous” electronic or mechanical patterns. For example, an analog watch …

A circuit in which the output varies as a continuous function of the input, as contrasted with digital circuit.

An Analog Signal is any continuous signal for which the time-varying feature of the signal is a representation of some other time-varying quantity, i.e., analogous to another time-varying signal. For example, in an analog audio signal, the instantaneous voltage of …

A positively charged electrode, as of an electrolytic cell, storage battery, or electron tube.

American National Standards Institute (ANSI) is an organization that establishes US and international standards. ANSI publications that are most applicable to printed circuits are those that define drafting procedures and documentation formats.

What’s an Antipad in PCB?   An Antipad, Anti Pad or Anti-pad in printed circuit board (PCB) refers to the void area around a via on internal plane layer, and which restricts other signal traces that should not be connected …

Aperture in PCB industry has 3 main definitions: 1. An indexed shape with a specified x and y dimension, or line-type with a specified width, used as a basic element or object by a photo plotter in plotting geometric patterns …

Advanced Product Quality Planning (APQP) is a framework of procedures and techniques used to develop products in industry, particularly in the automotive industry. It is similar to the concept of Design for Six Sigma (DFSS). According to the Automotive Industry …
