The Scientist and Engineers Guide to Digital Signal

The moving average is the most common filter in DSP mainly because it is the easiest digital filter to understand and use In spite of its simplicity the moving average filter is optimal for a common task: reducing random noise while retaining a sharp step response This makes it the premier filter for time domain encoded signals

DSP & Digital Filters

DSP and Digital Filters (2016-8746) Introduction: 1 – 4 / 16 • A signal is a numerical quantity that is a function of one or more independent variables such as time or position • Real-world signals are analog and vary continuously and take continuous values • Digital signals are sampled at discrete times and are quantized to a

Are digital filters the answer to all signal processing filtering requirements?
Digital filters, however, are not the answer to all signal processing filtering requirements. In order to maintain real-time operation, the DSP processor must be able to execute all the steps in the filter routine within one sampling clock period, 1/fs.
Can digital filters be used at a low frequency?
Digital filters can be used at very low frequencies. Speed limitation: The maximum bandwidth of signals that digital filters can handle, in real time, is much lower than for analog signals. Finite wordlength effects: Digital filters are subject to noises like ADC noise and roundoff noise that could lead to instability.
