What is Signal processing: Definition and 131 Discussions
Signal processing is an electrical engineering subfield that focuses on analysing, modifying, and synthesizing signals such as sound, images, and scientific measurements. Signal processing techniques can be used to improve transmission, storage efficiency and subjective quality and to also emphasize or detect components of interest in a measured signal.
Say I enter PHD w/ an outside MS. What percentage of coursework can I usually transfer? How many semesters classes need I retake?
I'm thinking of an MS in signal processing in EE, if that makes any difference. thanks.
Homework Statement
No problem statement - just the following questions.
Homework Equations
1.Display on a CRT is most similar to what reconstruction filter?
2.How many samples are required to represent a given signal without loss of information?
3.What signals can be reconstructed...
First, I'm not an engineer, so I don't know this topic very well.
Anyway, we were covering Fourier Transforms in one of my analytical methods class (chem major; NMR was the topic) and the phrase "discrete signal processing" came up.
In our particular case, we collect individual points on...
I'm doing signal processing using MATLAB.
But facing problem when doing Peak Detection.
This is the signal that I used for the processing:
This is what i wish to do:
a) the horizontal line is the threshold point and
b) the circle is the peak detection
Can anyone help me...
This is an unusual question in this forum but I couldn't think of a better place.
I'm new to Signal Processing. Currently I'm looking into localization methods using multiple sensors. This requires, I assume, some sort of "controlling" matrix that will eventually approximate the location of...
I want to ask how to process a pressure signal so that the signals can be smoothed / linearized, e.g. integrate, differentiate, rms, additive smoothing?
Hi all,
I'm considering doing a masters in either signal processing or machine learning. I have a bachelor's in electrical and electronic engineering, and have a bit of experience (internships mostly) in both industry and research. I was wondering if there are a lot of career opportunities...
Homework Statement
hello!
i'm given a signal h(t) = v(t)*g(t)
where g(t) is a distortion/noise that got added
and has a very low frequency compared to v(t)
i need to devise a method to clean up g(t)
The Attempt at a Solution
i'm thinking of to do the fft on the signal h(t)...

Hi all,
I'm having some trouble understanding the consequences of directly changing the frequencies in the spectrum of an audio signal. Let me give you an example:
Let's say I have some audio signal, which I convert to a spectrum (in LabView, using a
direct cosine transform (to avoid...
Career in DSP!
I am doing b.e electrical and electronics from bits-pilani , india.
I have just completed my second year.
I had a course on signal and systems(fourier, laplace, sampling etc.) in my fourth semester.It has aroused my interest in dsp field.
Can anyone here guide me on how to...
Is parameter estimation in DSP concerned with things such as bit error rates, maximum likelihood detection etc ... ?
If not, can someone point me in the right direction so I can find some learning material.
thanks

I have a task :
Two different signals will be used as input signal u . The first one is an AR model generated
signal. The second one is a speech signal recorded with 16bits/sample at 8kHz sampling rate. The name of the speech file is speech.mat

One subject that I've always been interested in, but have never found the proper introduction to is signal processing. I thought PF might be an appropriate place to ask (tough, I'm not even sure which forum it would be most appropriate, but since I'm stronger in math than physics, I'm posting...
Graduate School -- DSP, Signal Processing
What are the top graduate schools for signal processing?
I am currently looking at Georgia Tech.
Any other recommendations?
I would like (if possible) courses in radar.
Hello all. I am working on a problem for class that is taking some time data and changing it to frequency data. I am using excel and the fast Fourier transform(fft).
I am having a problem graphing the results. I am very new to signal processing.
I am only given the data which is 1024...
Hello All, I am currently taking Signal Processing & Linear Systems. I've come across my last problem for homework but can't find a way to do it. If someone can show me in the right direction it will be very helpful.
Thanks

The voltage f(t) = 2u(t) is applied to the circuit...
I have three courses that I can choose from: Electromagnetics or Digital Signal Processing II or Semiconductor Physics and Theory for my spring?
Which do you suggest?
Hi,
I am pretty new to Matlab and am trying to reduce the noise of a particular signal. I found this pdf online and found it to be helpful. However, I am having trouble figuring out what the freq=(0:79)/(2*n*dt) means. More specifically the 0:79 bit. Any help would be much appreciated...
Is it possible to perform some form of data correction by finding the variance/std dev and covariance?
I have a bunch data all related to a specific observation. For test purposes, i have 1000 samples of each data for certain condition.
I can find the covariance between each data under this...
I am currently working on a project to build a barcode scanner. I have built the apparatus to detect a signal and am able to view this signal on an oscilloscope, however I am wondering if it is possible to build a circuit to output this signal as a binary code on a series of LED's (or something...

Is the system y[n] = x[n] - x[n-1] time invariant?
Homework Equations

I say no, but there's one thing I don't understand. I think if you shifted the input, and then ran those samples through the system, you'd get x[n-n0] - x[n-1]...

Hi. I have a data gaussian g(t) and data that I suspect is a convolution (g*f). I want to find f(t), so I need to deconvolute (using Origin preferably).
If I convolute g*g, I get something very beautiful.
If I convolute (g*f)*(g*f), I get something very beautiful.
If I deconvolute...
