What is round off noise in IIR filters?

The analysis of roundoff noise for IIR filters proceeds in the same way as for FIR filters. The analysis for IIR filters is more complicated because roundoff noise computed internally must be propagated through a transfer function from the point of the quantization to the filter output.

What is round off noise?

Round-off Noise: Product of two W-bit fixed-point fractions is a (2W-1) bit number. This product must eventually be quantized to W-bits by rounding or truncation, which results in round-off noise.

What are the advantages of FIR over IIR?

FIR filters can achieve linear phase response and pass a signal without phase distortion. They are easier to implement than IIR filters.

What is noise What are the types of noise in signal processing?

In signal processing, noise is a general term for unwanted (and, in general, unknown) modifications that a signal may suffer during capture, storage, transmission, processing, or conversion.
