The hardware implementation of a fourth-order low pass digital filter using five microprocessors is investigated. It shows the maximum sampling frequency would be 111 KHz which is five times of the frequency for the singlemicroprocessor system.
The paper also suggests the implementation of a high speed 12 bit fourth-order digital filter with a maximum input sampling frequency of 1.2MHz, employing a single multiplier-accumulator.
