Abstract:Most existing FIR filter design methods are based on infinite
precision arithmetic and thus lead to filters which cannot be
readily implemented with microprocessors. Such infinite precision
filters have to be transformed into finite precision filters using
techniques such as coefficient quantization and rounding before
they can be implemented with hardware. Among finite precision
filters, FIR filters whose coefficients are restricted to a sum of
signed powers of two are particularly attractive as they can be
implemented without using any multipliers, which often greatly
contribute to the cost and complexity. In this seminar, the problem
of optimal approximation of a given FIR filter by a filter with
discrete coefficients will be discussed. An analytic approach to
the problem will be described.
