How do I know what order my digital filter is?

The order of a digital filter is the number of previous inputs (stored in the processor's memory) used to calculate the current output. Thus: 1. Examples (1) and (2) above are zero-order filters, as the current output yn depends only on the current input xn and not on any previous inputs.

What are the two types of digital filters?

There are two fundamental types of digital filters: finite impulse response (FIR) and infinite impulse response (IIR).

How many types of filters are there in DSP?

There are two types of filters in the digital realm: Finite Impulse Response (FIR) filters and Infinite Impulse Response (IIR) filters. They are very different in essence.

How do you design digital filters from analog filters?

Digital filters can be designed using analog design methods by following these steps: Filter specifications are specified in the digital domain. The filter type (highpass, lowpass,bandpass etc.) is specified. An equivalent lowpass filter is designed that meets these specifications.
