2. A type of filter that operates on analog signals before digitization, typically implemented with resistors, capacitors, and inductors
An analog filter is essential in signal conditioning before the ADC converter processes the data.
Um filtro analógico é essencial no condicionamento de sinal antes que o conversor ADC processe os dados.
This is primarily technical terminology used in electrical engineering, electronics, and signal processing fields in both Brazil and the USA. It gained prominence with the development of digital signal processing in the late 20th century as a way to distinguish traditional continuous-time filtering from newer discrete-time methods. The term is used identically in both English and Portuguese technical communities.
