Virrankäsittelykomponentit
Virrankäsittely, also known as signal processing, is a field of electrical engineering and applied mathematics that deals with the analysis, modification, and synthesis of signals. Signals can be anything from electrical voltages and currents to sound waves, images, and biological data. The goal of virrankäsittely is to extract useful information from these signals, enhance their quality, or transform them into a more suitable form for a particular application.
The field is broadly divided into two main categories: analog virrankäsittely and digital virrankäsittely. Analog virrankäsittely
Key techniques in virrankäsittely include filtering, which removes unwanted components from a signal; modulation and demodulation,
