Frequency Dependant Resistor 40 33 (5/23/2005 8:51:25 PM) comp.dsp What kind of thing, within linear systems theory, is a frequency dependant resistor? If I construct the IFFT of a frequency domain function is purely real I get what looks like a linear phase filter rotate... Bob

Cross Correlation and Noise Reduction in Mic Arrays 11 33 (4/3/2005 2:38:47 AM) comp.dsp I'm looking at a problem involving an array of microphone elements. The array is closely spaced, clustered within less than half the wavelength of the highest frequency of interest. The operations used to... Bob

LMS Pseudo Inverses of Complex Matrices 7 34 (1/28/2005 10:24:16 PM) comp.dsp I have an overconstrained system of equations (m equations in n variables with m>n) where the variables are complex. Using the Moore-Penrose pseudoinverse method of solution is giving me results that are te... Bob

Anybody Using S.F. Acoustic Mirror? 2 66 (12/19/2004 6:50:57 AM) comp.dsp Is anybody using Sound Forge (v5 and above) and Acoustic Mirror to calculate impulse responses from sweeps? I bought the old stand alone Acoustic Modeler DX plugin from Sonic Foundry when they marketed it s... Bob

Refresh - Method for cleaning noise from a measured sweep 11 26 (11/19/2004 5:32:01 AM) comp.dsp A while back there was a thread discussing how to effectively clean the noise and some reflections out of the measurement of the response to a sweep to be used for impulse response extraction in the audio b...

FIR Inversion and Division With Levinson-Durbin, Matlab Code 0 38 (11/13/2004 5:57:19 PM) comp.dsp Below are the Matlab functions for FIR inversion and division in the time domain employing Levinson-Durbin, a fast Toeplitz matrix solver. This question of FIR inversion comes up often so I thought I'd post it... Bob

Semi Annual Trim Reminder 3 33 (11/2/2004 4:45:01 AM) comp.dsp I wish I knew what it was about this group that makes people completely forget (or ignore) their format manners. It isn't usually apparent here but it is bad manners and the height of laziness to quote ever... Bob

A _really_ basic question 24 28 (6/17/2004 3:11:58 AM) comp.dsp What does it physically mean to say that the functions exp(i*w*t) are eigenvectors of linear systems? Bob -- "Things should be described as simply as possible, but no simpler." ... Bob
