This work presents the design and implementation of a phase-modulated signal generator, which allows a widerange of variation in its transmission parameters.The implemented Birds Beak circuit uses a minimum amount of FPGA resources.This was possible since the developed design stores a quarter cycle of the copyright, then the control logic decides which samples to take to obtain the established frequency and number of cycles per data, allowing a great variation.The output power of the signal is also configurable.In addition, the developed system allows data to be received through an external input or generated internally through a pseudo-random number generator (PRNG).
The circuit was implemented using an FPGA (Field Programmable Gate Array) and Canopies a digital-analogue converter (DAC).
