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.
