Voltage pros:
easy generation, detection
lots of engineering knowledge
potentially low power in steady state
Voltage cons:缺点
easily affected by environment
DC connectivity required?
R & C effects slow things down

Noise and inaccuracy are inevitable; we can’t
reliably reproduce infinite information-- we must
design our system to tolerate some amount of
error if it is to process information reliably.
