If you want to record your garage door opener signal in order to, for example, see the coded pulses you can do it with a RTL-SDR dongle. If

In signal processing, most of time we acquire a signal which frequency is unknown. For example, if we are taking EEG from an Emotiv headset, we can be

    Importance FMCW radars main applications are as altimeters, placed in aircraft, but also in the investigation of atmosphere, thanks to the sensitivity and spatial resolution that

As we did in our previous post, we are going to share with you a tutorial to learn about LTI Systems in the time domain and filtering. Therefore,

In this tutorial we are going to see how to create a waveform file by using Matlab and a free software from Rohde & Schwarz. First, have a look

Doppler Radar System Description The Doppler radar performance makes an optimum use of the transmitted power and its weight is appropriate to be used in aircrafts. In addition,

Comments added thanks to William Buller, from Michigan Technological University In this post we are going to review the main characteristics of radar signals and we are going

Following our last post about the FT Theory, now we will practice in Matlab with code exercises and solutions. The first thing you need to do is to

In this post we are going to see the theory behind the Fourier Transform in an understandable way so you can be ready to practice with our next

In this post we are going to review some basic concepts about Frequency Modulation (FM) to set the basis for our next post, which will be a Matlab tutorial,

In this post we are going to apply what we learnt about the FM signal’s properties in our last post. We will do some exercises in Matlab by

In this post, we are going to see a practical study of periodic signals in Matlab. We are going to post the code and the results here so

If you read our last post then you are ready to easily follow this tutorial in which we are going to study the PAM signals generation and their spectra. Now,

Theoretical Introduction In this post we are going to study and practice the basis of the FMCW Radar: we will analyse a practical example in Matlab in which

Communication systems play an important role in all the information transmission systems. Generally, in all the communication systems, the information in the source is processed through a modulator
