Analog Electronics
Analog electronics encompasses the design and analysis of circuits that process continuous signals, where voltages and currents can take any value within a range rather than discrete levels. Unlike digital electronics that works with binary states, analog circuits must handle infinitely variable quantities with precision, making them essential for interfacing with the physical world where most phenomena are inherently continuous.
From the operational amplifiers that form the backbone of signal conditioning to the oscillators that generate precise waveforms, from voltage regulators that provide stable power to data converters that bridge analog and digital domains, this discipline combines fundamental physics with practical engineering to create systems that sense, process, and control real-world signals with accuracy and efficiency.
