Hello,
In fact, I'm working on a project that aims to put a communication platform to interact with hydrogen sensor wirelessly.
The platform consists of an evaluation board from Xilinx ML505 (on which there is a Virtex 5) which will implement the baseband digital processing and another board (Software Defined Radio) for the analog front end that includes the blocks needed (modulator / demodulator, filter, LNA, PA, local oscillator) to communicate on the UHF band (900 MHz).
The platform requires a 12-bit DAC and an ADC 12-bit to adapt the two boards.
So I need help to generate a baseband signal (VHDL description) with a defined frequency, otherwise, I have trouble to describe the signal generator in VHDL
