Signal generation and evaluation using Digital-to-Analog Converter and Signal Defined Radio

In contemporary communication systems, Digital-to-Analog Converters (DAC), Signal Defined Radio (SDR) signal creation, and clock data recovery are essential components. DACs convert digital signals to analog signals, creating continuous waveforms. DACs provide versatility in the transmission of SDR by supporting a range of communication protocols. Clock data recovery enables precise signal recovery and synchronization at the receiver end. These elements work together to provide effective and high-quality communication systems across several sectors. With the development of quantum computing, these SDR systems also find extensive use in generating precisely timed signals for controlling components of a quantum computer and also for read-out operations from various specialized instruments. This thesis demonstrates an FPGA (Xilinx vcu118) with a DAC (Analog Devices AD9081) platform. It employs SDR for generating of periodic signals and also stream of bits which are then recovered using a simple Clock Data Recovery technique. The signal integrity of the generated signals and error-rate from the proposed Clock Data Recovery technique is also analyzed.
