How do you implement a FIR filter?

Structurally, FIR filters consist of just two things: a sample delay line and a set of coefficients. To implement the filter: Put the input sample into the delay line. Multiply each sample in the delay line by the corresponding coefficient and accumulate the result.

What are filters in signal processing?

In signal processing, a filter is a device or process that removes some unwanted components or features from a signal. Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal.

What is real time filtering?

Real Time Digital Filters can be used to filter a measured signal in real time. Filter characteristics can be defined by the user to meet the requirements of a specific application. Real-time digital filters are applied in the data conditioning phase.
