N2  - In this study, we investigate the FPGA schematicimplementations of finite impulse response (FIR) digital filters for threefundamental structures on Altera DE2-115 board without requiring any othersoftware packages such as DSP Builder and Matlab Simulink. First of all, a lowpass FIR digital filter is designed by using Matlab filter design and analysistool (fdatool) program. Then, the designed filter is implemented and simulatedon Matlab for a given input signal. After that, for three fundamental structures(namely direct-form, transposed direct-form, and symmetric direct-form) inliterature, the designed filter is implemented schematically on Quartus-IIsoftware and then each project containing different structure implementation iscompiled. Then, the digital filters implemented by each structure are simulatedby University Program Vector Wave File (VWF) simulation program on Quartus-IIsoftware. Simulation results show that the obtained results are the same as theones obtained on Matlab, which confirms that the schematic designs aresuccessfully implemented. Moreover, the implemented digital filters arerealized and successfully tested on Altera DE2-115 FPGA board. Finally, threefundamental FIR structures for various filter lengths from 11 to 51 areimplemented to compare them in terms of total logic elements, total registers,and total memory.
