analog circuit
Quick Summary
An analog circuit is a type of electronic circuit that processes continuously variable signals, unlike digital circuits which use discrete values. These circuits are often connected to devices that interact with the real world, such as microphones that convert sound into electrical signals or thermostats that respond to temperature changes.1
Analog circuits modify these signals, for example, by amplifying them or filtering out noise. The design of analog circuits is highly detailed, with every component's placement and connection being crucial to the final performance. Equations like Ohm's law ((V=IR)) are fundamental, but complex designs often require sophisticated computer simulations like SPICE to account for subtle effects and parasitic components.2
Historically, analog computers were used to simulate dynamic systems and solve complex mathematical problems, but they have largely been replaced by digital computers.3

As mentioned earlier, an analog circuit takes an infinitely variable real-world voltage or current and modifies it in some useful way. The signal might be amplified, compared with another signal, mixed with other signals, separated from other signals, examined for value, or otherwise…
