Abstract:
Nowadays, increasingly improvements in the digital technology and the advantages of using digital signal processing methods lead engineers to use digital signal processing instead of analog processing in variant domains. However, speed limitations in analog to digital converters (ADCs) and data transfer ports prevent its penetration to high frequency signals region. In this thesis, an Instantaneous Frequency Measurement (IFM) system that can measure frequency in the range of 2-18 GHz is implemented fully digital (DIFM) on FPGA. To do so, monobit sampling technique with the sampling rate of 10 GHz is selected, and GTX high speed serial port is configured to transfer digital data into FPGA. Moreover, different fast frequency measurement methods is investigated, then simulated with MATLAB and MODELSIM, and implemented on FPGA board afterwards. All of these methods are compared with each other, and finally self-correlation (Delta-phase) algorithm is preferred to other methods for its benefits, and optimally implemented on FPGA to use in DIFM final system
