1. ANALOG VS DIGITAL

2. Audio Voltage Ampere Signal Transistor Capacitor Hz GHZ AD convertor Decibels

3. AUDIO the field of sound recording, transmission, reception, and reproduction.

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

5. AMPERE SI unit of electrical current (how we measure an electrical current)

6. SIGNAL an electrical impulse or radio wave transmitted or received.

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

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

9. 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.

10. 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.

11. 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.

12. 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.
