Hi all,
I need to design a high-pass Finite Impulse Response filter having a normalized digital angular cut-off freq of 0.18pi rad/sec and an attenuation of 40dB at 0.1pi red/sec. To design the filter I am using the FDA-tool. Is it correct if I input the parameters shown in the attached screenshot? what is the appropriate value for input Wpass? and what parameters should I pay attention to achieve the specifications? Any kind of help would be highly appreciated.
