Intermediate Topic 18 of 50 Mobile, Embedded & IoT
Analog vs Digital Signals
Continuous versus discrete-valued signals.
How it works
Analog signals vary continuously; digital signals take discrete levels (0/1). Noise immunity makes digital reliable, while sensors start analog.
Where it is used
Interface design.
Common pitfall
Mixing grounds causes noise.
