Hello all,
I want to determine phase noise specs for a radar transmit signal at offset frequencies with respect to carrier but have not seen a direct, explicit formula for it. Can anyone help?
Hello all,
I would like to generate a basic radar loop (Transmit bw=400Mhz, f center=9.5Ghz) and downconvert it back to IF (750Mhz) with a matlab code but I cannot. Below is the matlab code for it, can anyone help?

Hello all,
I have a floating point Simulink model that I want to compare its performance to a fixed-point counterpart so I want to change the model to fixed point but I dont`t know how. The blocks need data type changes and I need to specifiy integer and fraction bit sizes. I know Simulink...
Hello all,
I am creating a simulink model in fixed-steps. All my blocks' outputs are double with one exception (altough I do not know if that is the source of the problem I will state) pre-lookup table.
When I run the Fixed Point Advisor at the check 1.2 Verify update diagram status I get the...
Hello all,
I am a systems engineer who directly after graduation(Majored in Telecommonications) started to work as systems engineer and still working for 4 years. Now I am continuing a master's study in Signal Processing.

Hello again,
A friend of mine proposed a single code fragment:
----
fid = fopen('text.txt','rt');
datas = textscan(fid','%f','headerLines',3);
data = datas{1}
fclose(fid);

and it worked! Wanted to announce here..
Hello there,
I have txt. files which are recorded by some oscilloscope in the format:

Hello all,
I want to determine the power level (dB amp) of (supposed to be wgn) random signal using oscilloscope data. I have compiled a code to do the job but when tried to verify my code for several different signals (periodic sinus, random gaussian) generated on MATLAB, I have seen that the...
Hello all,
I have done some market research and found a company that can partially meet our design reqirements. However, the carrier frequency data extraction is an issue to be dealt with and I asked for application notes on the RF Over Fiber companies but received no data so far.
Thank you...
Hello all,
I am trying to see if the following is possibly realizable:
I need to design an 1 GHz BW RF Receiver in frequency range 0.1-18 GHz. I want to collect RF at Antennae and convert it to Optic then send it to Receiver and convert Optic signal to Baseband or if possible get the Time vs...
Hello zorro,
Thanks for your help. Your approach was correct. I manually generated a 50 MHz array and multiplied the square to get my intended signal.
I got the spectrum desired.
Thanks a lot again.
Hello zorro,
y=x50M500M1MSINDIS means 50 MHz frequency sampled with 500 MHz for 1 Million samples with sin(x)-x reconstruction filter disabled. It is the name of MATLAB workspace file imported from a text file with same name. (MATLAB 2012)
Here are the matlab plots for y-time and...
Hello all;
I have collected samples from a periodic pulsed RF signal with following properties:
RF : 50 MHz
PW : 1usec.
PRI : 3 usec.
Sampling frequency : 500 MHz
Collected Sample # : 1 Million
with a scope.
I have imported data to MATLAB to take FFT with the following code:

Hello,
For testing purposes, we' ll need to show some kind of a time delay between RF and LVDS signals on different lines.
Can this be done on oscilloscope(a 4-channel Digital Phosphor Oscilloscope) without any unforeseeable impact on time characteristics or would I need any type of...
