Phase shift in the frequency domain - Problems!!1940 (8/31/2012 1:27:33 PM) Hi,
I apologise for the rather basic question.
I am attempting to use MATLAB to carry out a phase shift in the frequency
domain by the following process:
I have a time domain signal, x, with the followi... Lightbulb85
replacing 8th order bessel with FIR635 (9/3/2012 12:40:46 PM) we use a filter chip we can't get any more, at least not reliably. it's an
8th order bessel. I want to replace it with an RC and then do tight
filtering in FIR in the uC, a 32 bit integer processor.
I un... Jon
Switch-Synchronous Sampling in SMPS's5243 (8/22/2012 6:50:44 PM) Isn't there a belief that better (less noisy) sensor signals can be
acquired in a SMPS when the ADC samples at the switching frequency and
the ADC sample times are synchronized to sample between the switching... yates9428(616)
Filtering 60 Hz harmonics in cardiac electrogram1650 (8/21/2012 4:47:25 PM) Dear comp.dsp
I'm a ECE undergrad student. I'm using Matlab to clean up unipolar cardiac =
electrogram recordings. I expect signals between 30 and 500 Hz. However, I =

Asymmetric FIR filter from simmetric one?649 (8/29/2012 5:24:33 PM)
I need a lowpass FIR filter with a thin passband and about 50-60dB
attenuation in the stop band. The filter must introduce as little
delay as possible (6-10 samples max would be best). After a lot... mike9232(9)

Is it worth getting an M. Eng?950 (8/20/2012 2:25:37 PM) I was recently made an offer from a company and I plan on accepting it.
Part of the offer includes tuition reimbursement which got me thinking on
maybe getting a masters. Is it worth getting a masters (especi... Crandles
Carrier recovery system for QPSK29159 (5/24/2012 6:56:58 AM) Hi All,
I want to implement a carrier recovery system in Matlab for a
quadrature QPSK system. First i want to recover the phase offset and
then to recover the frequency offset. According to some digital
