Digital Filter
Digital systems are being used more frequently for filtering applications.
A common digital filter is the finite impulse response (FIR) filter, which
shifts incoming data through a series of registers. The output of each bank
of registers is called a tap. The output per time period is the sum of all
taps, which is calculated by multiplying each tap by a coefficient and
summing the products.
The filter’s frequency response is determined by the value of the
coefficients used in the design. In a linear phase response FIR filter, the
coefficients are symmetric, i.e., the coefficient for tap
coefficient for tap (
m
–
n – 1
), where
example, if there are 8 taps, the coefficients for tap 1 and tap 6 are equal.
Because the coefficients for tap 1 and tap 6 are equal, only half the number
of multipliers are needed to calculate the output per time period; using the
distributive property of multiplication, the taps with the same coefficients
are summed before multiplication, e.g.,
coefficient.
