The sample FIR is a quick and dirty low pass filter with linear phase. The design parameters of the filter are a

–3dB cutoff at Ω

= 30π rad/sec, ω

= 0.3π rad and an attenuation of 50dB at Ω

= 45π rad/sec, ω

= 0.45π

rad. For example, a sampling rate of 64000 samples/second (T

-1

= 64000 samples/s), yields a analog

frequency cutoff of 9.6kHz and the 50dB attenuation corner point at 14.4kHz.

xor_iodimm.c performs the XOR logic function on 3 inputs. The XOR is performed on the first two inputs

and the result output to the first output. The result of the second and third input XOR are sent to the

second output. The source code for xor_iodimm.c is available in /opt/samples/card_specific/

iodimm/dio.
