week 7 Flashcards
1
Q
why do you convert analogue to digital
A
- error and noise free transmission
- signal processing
- flexibility
2
Q
what 2 processes does analogue to digital conversion involve
A
- quantisation
- sampling
3
Q
what is quantisation
A
assigning a value X from a set of N values into which measurement range is divided
4
Q
what is sampling
A
capturing state of signal at fixed intervals
5
Q
analog vs digital
A
analog:
- continuous signal
- range of voltages
- low bandwidth
- susceptible to noise
- hardware inflexible
digital:
- signal, clock frequency
- fixed voltage
- high bandwidth
- noise immune
- digital hardware flexible
