Thank you Mr. Stephen!

I have a fixed ADC on PCB with 10MSamples/sec. The slope of the Signal is varying. Also the small reflections are to be measured. Is there any other possibility to acquire the reflections data without increasing the sampling rate? I am just putting my query in here, apologies to return the...

Hi, I am working on TDR (Time Domain Reflectometry). I send a 7GHz bandwidth fast rising edge (14ns) square wave into a coax. I get a return Signal. I have an ADC with 10Msamples/sec. I am using MPLAB IDE for coding the microcontroller. Now I would like to increase the Points on the...

Thank you Mr Baluncore! I will work on it and get back to you.

Thank you Mr Baluncore for your advice. Yes, it is Time Domain Reflectometry. But I have a question regarding Transmitting Chirp down the transmitting line. In this process, the pulse is stretched. For example a 1ns pulse may be 1microsecond Long before it is upconverted and transmitted. This...

Sir, Thank you for your Response! Iam working the Time Domain Reflectometry. I have a square waveform with 14ns rise time and 350ns Duration generated by a 7GHz Transistor which is controlled by a micro-controller. This is my incident pulse. The Information that I am interested in is the...

Its a square wave and I must over sample the ADC to increase the sampling rate which increases the number of sampling points. But that is not enough in my case, I guess.

No, its just a single reflecting pulse.

Hi Stephen, I have the raw data from the UART in real time. The set of data is in decimal counts, for example: 1;4048#gy;1;4052#gy;1;4050#gy;1;4050#gy;1;4050#gy;1;4050#gy;1;4052#gy;1;4050#gy; and so on... I cannot find the way to crack this!

Hi, I am new to world of electronics and to high frequency Domain. But I am working on a design where I have a coax of 30cm length. I have used an external oscillator to generate 7GHz fast falling pulse. I am using a Controller to control the oscillator. Now I have a pulse of about 350ns...

Thank you Mr Stephen for your response. The data I am measuring is the reflection (based on radar). At the moment I have fine reflections and like you mentioned, my next step is to interpolate to observe the reflections in time more clearly. I have this experiment running on MPLAB and I am not...

Hi I am new member and I am new to the Signal processing so I hope I could get some help from the members to able to understand the concepts. I have a Signal. I have a 10Msaples/sec ADC. I view the Signal on an Oscilloscope which has 20Gsamples/sec sampling rate. The Point where I am...
