  1. 1. Implementation of a Low-Cost Analog-to-Digital Converter for Audio Applications Using an FPGA

    Master-uppsats, Elektroniksystem; Tekniska högskolan

    Författare :Johan Hellman; [2013]
    Nyckelord :ADC; Sigma-Delta; FPGA; LVDS;

    Sammanfattning : The aim of this master’s thesis is to implement an ADC (Analog-to-Digital Converter) foraudio applications using external components together with an FPGA (Field-ProgrammableGate Array). The focus is on making the ADC low-cost and it is desirable to achieve 16-bitresolution at 48 KS/s. LÄS MER
