Hi, I want to design a complete AM receptor and I don't know how to design the RF mixer to convert fo Intermediate Frequency. I need to use only matlab code, not Simulink. The first idea I have is to multiply the RF and LO signals and then to filter with a passband the IF, but I don't know how to do that. Any suggestion on code would be helpful!

Hi there! I have an assignment that goes as follows: Pulse compression by using a Linear FM signal 1) Consider a (real) Linear FM signal with a center frequency, f0= 1250 MHz, a bandwidth, B = 100 MHz, and a length, T = 0.15 ?s. - What is the required sampling frequency, fs? - Derive an
Read the matlab help aboit IIR design methods. fdesign.lowpass('N,Fc',...) is only valid for FIR. Apart from this point I don't agree with your assumption about "better lowpass IIR filter". FIR is basically good, although order of 31 is insufficient for a good lowpass filter with fc/fs = 4/100.

Hello I'm going to establish processing of electro-optical signals, actually a reception/detection of weak optical pulse (not LRF though the principles are close). I have certain processing in my mind to try in matlab simulation (actually tried the basic steps of one in Excel, looks not bad..), however I did not apply matching filter to the recei
I am trying to do something which resembles time division demultiplexing in Simulink/ matlab. I wish to implement the following: 1) I have 3 control signals - c1, c2 and c3. 2) I have 3 output variables - out1, out2 out3. 3) I want that the output of my system should append data to i) the variable out1 if c1 is high

Hi I want to simulate a new modulation scheme named DCSK for Differential Chaos Shift Keying. this modulation does not use sinusoidal signals as base signals, but uses chaotic signals (a noise-like signal). for each symbol to be sent, we have a signal consisted of N real samples. I want to pass this signals through a (...)
I have a problem where I have to implement Stationary Wavelet Transform and I am constrained that I can only up sample my input and not the filters. Is there a way to map convolution relationship between signals this way? On in matlab syntax: conv(upsample(A,2), B) == conv(upsample(B,2), A) where A is input, and B is filter co-efficients.

Hi, I currently have the EMOTIV EPOC headset including research SDK with me. I want to monitor its individual channel data in LabView. Currently they have the toolbox for matlab but not for labView. There is a hack library for labview but I think it is unable to provide access to individual channel. I want to analyse each individual channel i
I've done data telemetry with matlab before using matlab's built-in serial port functionality. But that means you need to build the hardware to sample the EEG signals, and send them to the PC via RS232 or USB. There's a considerable amount of hardware and software design involved in that. Alternatively you could buy a DAQ module, like (...)
