Digital Systems (1/2)

Digital systems operate on discrete elements of
information




Numbers (e.g., pocket calculator) -> “digits” ->
“digital”
Letters (e.g., word processor)
Pictures (e.g., digital cameras)
Digital systems



Cell phone
Digital camera
Industrial process controller, etc.

Digital Systems (2/2)

Some systems use continuous information



Analog clocks
Film cameras
For a digital systems to operate on a continuous
data, it needs to quantize (digitize) that data first

Digital Thermostat


Purpose: control room
temperature
Digital thermostat



Senses temperature and
converts it to a digital
representation
Simple processor compares
current and set temperature
If too cold, heater circuit is
turned on

OK, but how is the conversion
done?
How is digital information
stored?

Digital Audio
processing or storage of
digital signal (e.g., MP3)

Analog to Digital Recording
ADC





Microphone converts acoustic waves to electrical energy. It’s a
transducer.
Analog signal: continuously varying electrical energy of the sound
pressure wave.
ADC (Analog to Digital Converter) converts analog to digital electrical
signal.
Digital signal: digital representation of signal in binary numbers.
DAC (Digital to Analog Converter) converts digital signal in computer
to analog for your headphones.

The Digital Audio Stream

A series of sample numbers, to be interpreted as
instantaneous amplitudes

one number for every tick of the sample clock from previous
example:
5 6 7 7 5 4 3 1 2 5 7 5 7 4


This is what appears in a sound file, along with a header
that indicates the sampling rate, bit depth and other things
Each number is then converted to binary and stored in a
register
101 110 111 111 100 011 001 001 010 101 111 101 111 100
