Title:
FLOATING POINT DIGITAL TRANSVERSAL FILTER
Document Type and Number:
WIPO Patent Application WO1998025343
Kind Code:
A3
Abstract:
A digital finite impulse response (FIR) filter having a shift register for receiving a digital signal, a counter for counting pulses in a sampling signal and a look-up table read-only memory (ROM) having address inputs coupled to the outputs of the stages of the FIR filter and to the outputs from the counter. The output of the ROM forms the filtered signal. This digital filter approach allows for a balance between cost and performance and is inherently flexible due to the programmable nature of its core device (ROM).
