Me: a consultant in algorithms, circuit design and software. You: a probability density function for a unit vector in three dimensions, flexible enough to approach a Gaussian in the limit as your...

Detecting small signals with large noise [12 articles]

The current problem of finding the "black boxes" from the Air France flight that crashed would seem to be another small signal/large noise problem, maybe one that signal processing could help. My...

formant frequency vs. fundamental frequency [7 articles]

What exactly is the difference between the fundamental frequency of a sound and the first formant frequency? To me they look the same ...

log energy of audio frame [3 articles]

Hi, sorry to post 2 questions in the same day but Ive been searching all day and got nowhere. Im trying to compute the log energy of an audio frame. I am aware that the result of my calculatio...

questions about wireless channel???

Hello My name is Dania, I am new in WiMAX, I am trying to simulate wireless channel for subscriber station (SS), I am using the formula received signal power (RSP): Pr=Pt P0 xR(do/d)α Or i...

Are harmonics real? [57 articles]

Hi there, I am involved in the machinery vibration analysis field. We use FFTs to study vibration from rotating machinery. If you look at the FFT “rules”, an impulse will give a spect...

[OT-ish] It's Spring, when a young man's thoughts turn to [37 articles]

Getting the heck out of engineering school while he's still young! For some reason, this year I'm getting mail directly from the "help me I have a month to get my senior project done" crowd. I a...

Correlation PAM symbols [2 articles]

I've a Digital PAM signal x(t) = sum ( a_k * p(t) , k) The symbols a_k are defined as follow: a_k = b_k + x*b_(k-1) where b_k = { -1 ; +1 } a_k represent the kth symbol in the message sequ...

Designing a programmable filter for a wide range of bandwidths [5 articles]

Hi I have been tasked to design a programmable bandpass filter that can be used for a range of bandwidths from 50kHz to 30MHz. I am new to the field and only have limited experience in building s...

python psd [5 articles]

Hi, I am trying to take a PSD of an FSK signal that I've been fooling around with....I wrote it in python with the help of a post someone put on this board a while back. Here is the code: #!/usr/bi...
