I would like to design a 8x upsampling filter for 32Khz , 44K , and 48K sample rate . How to optimize the coeffiecient for three of the sample rate . Using the matlab , i only can assume the sample rate of the input signal is one the them like 44.1K .
Hi, I want to use interpolation (upsampling) in my project. The process as explained in DSP books is first adding L-1 zeros between between each sample and then low pass filtering with cut off frequency of Pi/L .How should such filters be designed? Any more information about this topic in general is appreciated. Thx.
Hi, 1- Pulse shaping filter reduce side lob level and interference to other channel frequencies, but we have two choice for implementing Raise Cosine filter, (a) using analog filter after D/C converter, or (b) using upsampling for practical possibility of digital implementation. 2- sqrt(100) is because after upsampling signal power decrease 1
i hav a cos signal ...first i want to downsampling wid 2..and then using dat signal i want to upsampling by 3.. Added after 3 hours 37 minutes: PLz help me doing dat... in matlab...
Is this a simple sinusoid? (i.e. sin(t)?) or is it a sinusoidal carrier with a modulated baseband signal (like a simple AM/FM modualtion)? Does the modulation need to remain intact on the harmonics (remain uncompressed due to upsampling)? If it's a simple sinewave, you could simply do 1*sin(t) + 0.7*sin(3t) + 0.45*sin(5t) + 0.38*sin(7t) + 0.29*s
I did not understand your methods for upsampling and downsampling. Why you dont use direct matlab operators for this: downsample(x,n) and upsample(x,n)? it's very simple to know. You can use function of matlab. for example: downsample help .
Can anyone please tell me what I need to do to enable me make MAPLAB plot the following outputs against time i.e. 1. Here I am differentiating the system step response, to show that this give the impulse response, but how do I make matlab do ?plot(t,x)? where t is 0 to 8ms and x is the step response differentiated. clear num=[0 0 20210
I am running SuperNEC with matlab 6.1. When I create a structure expecially a more complex one like a cone or a parabola, it takes a very long time to make the structure. It almost takes longer than to run the simulation. Has anybody else experienced this as well? Is this normal?

Hi "matlab 5 User contributed M-Files" 1. -> t tnx
i have to make this 2 programs, if anyone could help me out, i would apreciate it: 1- Write a matlab program to compute the first L samples of the inverse of a rational z-transform where the value of L is provided by the user through the command input. Using this program, compute and plot the first 50 samples of of the inverse of G(z) from Eq. 3.3

Dear friends: Is it possible to use matlab code (or code translation) in a development under Delphi or Visual basic?. How can do it , what's the better way? I understand that matlab provides a compiler to C, C++ code, but how can I link this code with a delphi application? Thanks great peopple Nebisman

Hi all, I wanna code a matlab program that calculates maximum gain for a given transistor S parameters and draws constant gain circles for a microwave amplifier. eg. for constant gain circle: GA=Gamax-1.5dB . Then after selecting some gammaS values on that circle, for each gammaS I'm gonna determine gammaL that lie on constant (VSWR)out=1.7 a
I have a data file of a signal I captured on my oscilloscope, the data contains time and voltage for each measurement. Is it possible to import this text file into matlab and create a DSP model that uses the data file as input and runs a filter algorithm on it and then somehow using SystemGenerator export that to a VHDL program and dump the whole f

Hello all, Do you know how to simulate a simple digital (or mixed) circuit with matlab? I mean a circuit containing only a few discrete logic elements(and, or, nand ...), flip-flops and also some opamps, resistors and capacitors. I don't mean a FPGA circuit(xilinx or other)! Is there a kind of schematic editor with library of the above menti
