Description: Any Band-Pass filter may be converted into a tunable filter with
a single tuning parameter through the use of a new Tunable
Heterodyne Band-Pass Filter concept in which the frequency of
the heterodyne signal is adjusted thereby translating the entire
filter transfer function in frequency. If the fixed filter is
selected to be a narrow-band band-pass filter, the new Tunable
Heterodyne Band-Pass Filter concept can be used very
effectively in the elimination of narrow band interference in
wide-band communications or control systems. A single-chip
version of this tunable filter can be constructed using a Xilinx
Virtex XCV800 chip. The resulting filter is a flexible tunable
band-pass filter that can be varied from DC to n/2 or from n/2
to n depending on the parameters of the fixed output low-pass
filter.

Description: FFT-based FIR Filter is a unit to perform the finite impulse responce filter based on the Fast Fourier Transform (FFT). It performs the convolution of the unlimited signal sequence with the synthesized impulse responce of the length of Ni=N/2 samples, where N = 64, 128, 256, 512, 1024. The data and coefficient widths are tunable in the range 8 to 18. -FFT-based FIR Filter is a unit to perform the finite impulse responce filter based on the Fast Fourier Transform (FFT).
