In the field of wireless communication, the use of modulators is very important. These devices can be used to transmit information by means of a radio wave to a receiver. However, in order to be able to do this, the receiver must have a certain capability. Thus, in the case of a mobile device, this means that the device must be able to receive and process the wave modulated signal.

In the case of the AM-FM Modulator, the signal is a modulated radio wave, which means that it has a constant frequency, but the wave has a variable amplitude. Thus, this application is able to make a graph of the signal.

The application can be used as a sample of points in the two-dimensional space, in order to make a graph of the signal.
