Describe the software techniques used for improving the signal-to-noise ratio of an electronic system.
Signal-to-noise ratio (SNR) in an electronic system measures the level of the desired signal relative to the background noise. Improving SNR enhances system performance, accuracy, and reliability. Software techniques play a crucial role in mitigating noise and extracting the useful signal.
