WebA low-pass filter is a filter that allows low-frequency signals to pass through while attenuating (reducing) high-frequency signals. It's commonly used in signal processing and communication systems. To discretize a low-pass filter, we need to convert the continuous-time filter transfer function into a discrete-time transfer function.
