In a FHSS system like Bluetooth, how is synchronization to the hopping sequence done? For example, for a specific hop sequence, is a special code sent at the beginning of a frame on the initial hop channel by the FHSS "master" and all slaves listen in and synchronise? Is short-term stabilty assumed good enough that synchronization can be mantained through all channels in the hopping seque...


What does 'M' mean in RS(544, 514, T=15, M=10)?

Hi, I know RS code has a 't' parameter, but I don't know the last one in RS(544, 514, T=15, M=10). Can you tell me that? Thanks,

Separate two sinusoids with very close frequencies (5 Hz difference) in an audio signal, with good time-domain resolution

Started by Random6wx3e3qvwp in comp.dsp7 months ago 3 replies

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,...

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...
