Removing DC and low frequency noise from a spectrum

In a previous post, I asked about removing a DC spike from a spectrum generated by a quadrature receiver. I have been able to remove the DC spike but the spike...
Rabbit Ear Artifact At Image Frequency of Complex Downconverted Pulse Train

Hello,
I have created a Matlab simulation of a series of band-limited sinusoidal pulses indexed 1:N, spaced evenly in "slow time" each with a starting phase that...
Is there any reliable implementation method of IIR filters with pole positions very close to the unit circle?

Thank you for reading this in advanceI approximated an FIR filter to an IIR filter using the balanced model truncation method.After this, I have got very similar...
Hi, I have a PDM signal and I wanna convert it to a PCM signal. This signal is sample at 1MHz. This is the process that I am following:Filter the signal with a FIR...
'Alchemical' Forecasting and Restorative Up-Sampling

Dear DSPRelated friends:It's been a number of months since I prematurely tried your patience with ideas so far 'out-of-the-box' that I could be paying you for therapy...
I am curious about the usefulness of IIR filters above 2nd order in DSP applications. I know that first order IIR's are common, and presumably so are biquads. ...
Hello, just a quick note to let you know that we are fully aware of the spam posts that made it into this forum lately, despite our spam filtering system. The...
GNURadio BPSK Position Costas Loop and Clocksync

Hello folks,I'm having a problem understanding GNU Radio and the BPSK examples right now.In all examples in the www, a clock sync block is used first after reading...
Calculating optimal loop point in audio sample

(Disclaimer, I'm self-taught and mostly a beginner when it comes to DSP)
Hi! I've recently been working on a problem to find the optimal loop point in an audio...
