I have an audio signal which is a mix of: * a 2000 Hz sinusoid, beginning at 1.00 sec, without fade-in/fade-out * a 2005 Hz sinusoid, beginning at 1.031 sec, with a slow fade-out at the end * background noise (link to the WAV file: https://file.io/jo0h9V) (In reality it's even more complex: the sinusoids can also vary in amplitude...) Question: How to separate the signal into t...

who design electronic products. I expect you are well aware of the price you can buy ready-made modules to do all manner of things from China or other far east countries. How is it possible to survive nowadays with such competition. I realise not all of the stuff is quality of course but some are more than satisfactory. I recently saw a composite video to HDMI convertor and know a f

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...

Hi. Is there a way I can access posts made on comp.dsp during March of 2008? Thanks. [-Rick-]

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...

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? ...
