Electricity and electronics
From electrons to bits
Information and electrical signals
1. How is information communicated electrically?
2. How do you extract information from a signal?
3. How are analog signals communicated digitally?
A signal is a function of time and/or space
,Numbers in decimal (10) and hexadecimal (16) notations
,Guillermo Marconi invented the radio communication, in 1895
Fundamental Model of Communication
M(t) : message ifv tijd
x(t) : coded message
r(t) : corrupted version of message
^m(t) : approximation of the message
, Where is the information in a signal?
Meer dan 10^15: zien we niet, voelen we wel branden
Ionising: hoge energie → particle is damaging the matter
Periodic waveforms
