I have a Kalman filter which estimates pitch and roll for a stabilised platform. It is a steady-state kalman filter so no great computational overload - I calculate the gain matrix first and then go into the while loop forever. In the loop there is also controllers Lag lead PI type. To get a high bandwidth I sample at 10kHz overall but I am finding that the Kalman filter doesn't nee

Hello! I'm new to DSP and programming, so I wonder how you guys did DSP programming in Atari days back in 80's. How did you figure out to do it? I guess education flow is something like that: 1) Learn Assembly language; 2) Get and learn Atari or IBM PC technical reference manuals; 3) Read some DSP books; 4) Start programming simple batch programs; Am I right? Can you please sug...

This is a long term question. We are in the process of building an Internet website that will allow the users to experiment, learn and ask questions about distances, angles, trajectories, ballistics and sounds related to a very specific event. This is the website where we plan to host the simulations, data, etc. Free Open Source 3D Model of Dealey Plaza http://dealey-plaza.org/ That...


What is the phase margin for a PLL of critically damped?

Hello, all: I read an online PLL tutorial, which says "the design of critically damped loops, a PM of about 70 degrees, does not lead to the fastest settling time for third order CP PLLs." It is known that a critically damped second order loop has zeta=1, i.e. two real roots of the same value. But I can't get its phase margin 70 degrees. What do you think about phase margin remark? ...


All-digital symbol timing recovery scheme constraints?

Dear All, In page 8 of http://www.cs.tut.fi/kurssit/TLT-5806/Synch.pdf it is stated: All-digital symbol timing recovery scheme requires higher-than-symbol-rate sampling. If this statement is correct what should be the minimum ratio? We have also a constraint on the max sampling rate of the ADC. It is 2.2x symbol rate. If we sample at 2.2x symbol rate should we also adjust the Matched filter...

I have the absolute amplitude of a digital signal that I want to auto correlate with self , also cross correlate with a different digital signal [ absolute magnitude ] . I'm using a complex 1d fft to implement this . I only have the absolute values of the spectra to work with ; where the absolute value is defined as : square root of (Real^2 + Imaginary^2). After multiplying the a...


Averaging of phase noise?

Hi all, My most basic question can be summarized as: "Can phase noise be averaged out?" And subsequentially, is there a difference if the input signal is a sinusoid or wideband? What happens after averaging infinitely many times? My first reaction is: No, it can't (at least not in a similar manner as white noise where SNR is increased by 10dB for every additional 10x of averaging) becau...
