Analog
Analog and digital signals are a means of representing information. An analog signal is a continuously varying signal, so called because it is analogous to the original data.[1]
Description
Analog is voltage. It is a real-world parameter. An analog circuit involves many paths between the input and output, influenced by factors such as noise, distortion, amplitude, power, and power supply current. The analog designer must optimize the circuitry to manipulate the analog information correctly.[2]
In electronics
Commonly seen as in transistors (in non-switching mode), RC filters and many other circuits.
In synthesizers
Analogue synthesizers use analogue circuitry such as Voltage Controlled Oscillators to generate simple waveforms such as square waves and sawtooth waves and Voltage Controlled Filters to process the waveforms. Both analogue and digital synthesizers produce an analogue waveform (as a variable voltage electrical signal) at the output.[3]
