| http://www.w3.org/ns/prov#value | - This paper proposes method for self-programmable Variable Digital Filter (VDF) design based on FPGA. Taking finite impulse response (FIR) digital filter as an example, we implement a digital filter system by using Custom embedded Micro-Processor, programmable FIR macro module, coefficient-loader, clock manager and A/D or D/A controller and other modules.
