Hello,I am studying the following differential encoder:where the quantizer is defined as \( Q(y) = \text{sgn}(y) \)and I would like to be sure I understand it correctly,...

Hi!I am working on converting a floating point MATLAB code into fixed point C code. The code is to be run on a DSP platform, the specifics of which are yet to be...

Hi all:Can anyone suggest a good way of doing DTMF-like tone detection by determining the (known) frequency difference between limited time duration tone-pairs?...

Hi, If my understanding is correct, most of the 802.15.4 receiver implementations perform frame synchronization i.e. find the start of the frame using the preambles...

Hi Everyone,I'm working on a speech vocoder and have so far been able to use the SPTK functions to achieve most of this. However I'm confused as I want to be able...

Hi all I am working on colored noise (reverberation) rejection algorithms. One approach present in literature is through prewhitening filter. In this approach as...

Dear signal processing enthusiasts: 

• I am forced to cut off a part of a multi-frequency signal, creating a "gap" as shown in the figure. (only one frequency to simplify illustration). 
• If I inject part A of the signal into a FIR which has linear phase vs frequency, and set the FIR to have a group_delay proportional to the gap length, the output's phase doesn't change, and hence the stitched signal has a phase jump.
• I am looking for a filter that would let part A propagate through, to the point where its phase matches part B's phase. Does such a filter exist?

...

How does one delay a signal and allow its phase to propagate vs time with a specific slope or rate? How can one -digitally- simulate the effect of a propagation...

Hi guys!I wonder if you could recommend any books about "control systems" -- the basics, maths, plots etc. and of course some (common) real applications. This is...
