AUDIO

•the field of sound recording, transmission, reception, and reproduction.

VOLTAGE

• the potential difference in charge between two points in an electrical field. 

AMPERE

• SI unit of electrical current (how we measure an electrical current)

SIGNAL

• an electrical impulse or radio wave transmitted or received.

TRANSISTOR

• a semiconductor device with three connections, capable of amplification in addition to rectification.

CAPACITOR

• a device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator.

HZ

• The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second.

GHZ

• One GHz represents 1 billion cycles per second. The speed of microprocessors, called the clock speed, often is measured in gigahertz. For example, a microprocessor that runs at 200 GHz executes 200 billion cycles per second.

AD CONVERTER

• An analog-to-digital converter (ADC, A/D, or A to D) is a device that converts a continuous physical quantity (usually voltage) to a digital number that represents the quantity's amplitude.

DECIBELS

• a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.
