GCES computes science key terms

Analogue

A continuously changing sighnal that can be found in nature.

Digital data

The binary representation of an analogue signal

ADC

The process of converterting a sound so that it can be storedon a computer

DAC

The process of converrting a digital signal back to analogue form

sampling

Taking a snapshot of an analogue signal at one single point in time

Quantisation

mapping a reading/snapshot to a binary value

sound wave

The whole section of the wave

Ampituide

The value of the wave(y-axis) at a given piont in time (x- axis)

Bit depth

The munber of bits needed to represent the range of values on they y- axis

y-axis

All binary values

X- axis

All time values

sample internal

The time between samples measured in seconds

sample rate

The number of sound samples taken per second, measured in hertz
