Description

ABSTRACT:
The filter has p stages, p being the number of bits on which are expressed the digital filtering coefficients. Each of the stages has a charge transfer shift register, called the signal register, receiving the analog signal E(t) to be filtered and a charge transfer shift register, called the coefficient register, receiving the M bits of the same weight of the M filtering coefficients. The filter also has an operator which multiplies the signal E(t) by each of the M filtering coefficients and then summates these various products to supply the output signal S(t) of the filter.
