Group delay in a multirate system

Recently, I have worked on a multirate system, the delay from the input and output found from the cross correlation was far off from the theoretical result. I don’t...
I'm coding up an implementation of a filter and to test it I would like a set of coefficients. Does anyone know how to make filter coefficients such that:it can...
I'm wondering if anyone here can trace the history of DSP notation. There's no universally-agreed-upon set of conventions, as far as I'm aware. When I discussed...
A few months ago, this community tackled the first FPGA FAQ titled When (and why) is it a good idea to use an FPGA in your embedded system design?. Your contributions...
Deriving velocity from accelerometer data

Hello, I am currently using an accelerometer for measuring the vibration signatures in rotating machines. But the requirement has changed now, to have the velocity to...
FSK demodulation with repetitive impulse jammer

Hi,I demodulate FSK (46 ks/s,3600/4800Hz,1200 Bd) and I have regular fat jammer pulses every 221 samples. Filtering away the pulses outside the useful spectrum 2k6-5k8Hz...
I am a hobbyist programmer, and for "fun" are trying decode signals from a wildlife tracker to assist with a local conservation project.With assistance from the...
Important Events in Our DSP Work

I believe there are two equally important events we can experience in our DSP work. The first kind of important event is when we examine the results of our designed...
I am looking at the pre-release Analog Devices AD9084 -- APOLLO MxFE. This has 4TX and 4Rx and ADC/DAC at 20/28 Gsps. There is also a less capable but similar...
