Match n Freq

Pulse shaping is generally used for communication devices, especially when it comes to radio frequency signals. The basic idea behind it is to modify the actual shape of the signal waveform, in order to fit a certain frequency band and filter the pulses according to a given set of parameters.

Match n Freq is a software utility that allows you to perform complex calculus functions and equations, which aim to reduce the intersymbol interference of the communication signals and minimize the total amount of distortion. Hence, the application functions as a pulse shaping filter that can find the pole-zero locations of a transfer function for a matched filter.

As far as the intersymbol interference goes, the distortion reduction is achieved by employing pulse slimming techniques, which enable to you properly filter the desired signal. The tabbed user interface allows you to enter all the required data in a predefined order and it also offers explanations for every requested value.

After you enter all the desired data, you can run the program and obtain the results. Depending on the capabilities of your computer, the process can take a few minutes, after which the application displays a text output containing the solution, as well as a graph to illustrate the results. You can also customize the plots according to your preferences, by choosing the color setup and adjusting the grid layout.

You can also make use of the provided demo samples, which give you an idea about what the application is capable of and also a template for your own data. An extensive amount of tips and suggestions are available as well, which offer you advice and instructions on how to enter the values and reduce the compiler runtime.

Despite the fact that the tool is aimed toward experienced users that are familiar with the concepts used throughout the application, Match n Freq provides you with enough documentation and examples to get you started right away, as long as you have some basic notions when it comes to electronics and pulse-shaping techniques.
