Collaboration diagram for Filters:

Classes
class	gr_adaptive_fir_ccf
	Adaptive FIR filter with gr_complex input, gr_complex output and float taps. More...
class	gr_fft_filter_ccc
	Fast FFT filter with gr_complex input, gr_complex output and gr_complex taps. More...
class	gr_fft_filter_fff
	Fast FFT filter with float input, float output and float taps. More...
class	gr_filter_delay_fc
	Filter-Delay Combination Block.The block takes one or two float stream and outputs a complex stream. If only one float stream is input, the real output is a delayed version of this input and the imaginary output is the filtered output. If two floats are connected to the input, then the real output is the delayed version of the first input, and the imaginary output is the filtered output. The delay in the real path accounts for the group delay introduced by the filter in the imaginary path. The filter taps needs to be calculated before initializing this block. More...
