In fairness to the OP we ought to mention the possibility of polyglobular phase-incontrovertible Tchebyshev locus diagrams. I find them invaluable for completing my sub-fusc harmonic variance charts for phase-denibulized channels. -- Jonathan Bromley, Consultant DOULOS - Developing Design Know-how VHDL * Verilog * SystemC * e * Perl * Tcl/Tk * Project Services Doulos Ltd., 22 Market Place, Ringwood, BH24 1AW, UK jonathan.bromley@MYCOMPANY.com http://www.MYCOMPANY.com The contents of this message may contain personal views which are not the views of Doulos Ltd., unless specifically stated.

Hai, Between 0.00001 Hz or less and 100GHz or greater depending on the application Can i say the cutoff frequency range can fall anywhere inbetween 0.0001hz to 100Ghz for communication and multimedia application..?? Variable ratio multitap with adaptive confocal formalized feedback can u suggest among the following which is the optimal filter design method for the above applications.. 1.equiripple 2.window 3.constant least squares 4.complex equiripple 5.interpolated FIR regards, faz On May 31, 3:05=A0pm, Jonathan Bromley <jonathan.brom...@MYCOMPANY.com> wrote:> On Sat, 31 May 2008 09:48:17 +0100, "Icky Thwacket" wrote: > >>And which is the optimal FIR filter design > >> method suited for that?? > > >Variable ratio multitap with adaptive confocal formalized feedback > > Really? =A0In fairness to the OP we ought to mention the > possibility of polyglobular phase-incontrovertible > Tchebyshev locus diagrams. =A0I find them invaluable for > completing my sub-fusc harmonic variance charts for > phase-denibulized channels. > -- > Jonathan Bromley, Consultant > > DOULOS - Developing Design Know-how > VHDL * Verilog * SystemC * e * Perl * Tcl/Tk * Project Services > > Doulos Ltd., 22 Market Place, Ringwood, BH24 1AW, UK > jonathan.brom...@MYCOMPANY.comhttp://www.MYCOMPANY.com > > The contents of this message may contain personal views which > are not the views of Doulos Ltd., unless specifically stated.

Hai, Can i say the cutoff frequency range can fall anywhere inbetween 0.0001hz to 100Ghz for communication and multimedia application..?? Yes probably Do u mean to say that for communication and multimedia application i can design a FIR low pass or High pass or band pass or band reject filter with cutoff frequency fall anywhere inbetween 0.0001hz to 100Ghz?which means can i select cutoff frequencies of FIR LP.HP,BP,BR filters in this range?? regards, faz On May 31, 6:04=A0pm, Frank Buss <f...@frank-buss.de> wrote:> Icky Thwacket wrote: > >>Can i say the cutoff frequency range can fall anywhere inbetween > >>0.0001hz to 100Ghz for communication and multimedia application..?? > > > Yes probably > > But a 100GHz cutoff frequency is required only to avoid quantum matter > aliasing with high resolution graviton lenses and holoemitters. > > -- > Frank Buss, f...@frank-buss.dehttp://www.frank-buss.de,http://www.it4-syst=ems.de

Ok, at the risk of spoil the party: Of course, before writing this as an answer for your homework exercise, you should think a bit (or trying Google and Wikipedia) about the frequencies of audio and video, the usage for filters and what are the reproducer limits, like speakers. -- Frank Buss, fb@frank-buss.de http://www.frank-buss.de, http://www.it4-systems.de
