   Sammanfattning : To deal with the wide dynamic rage necessary for a radio receiver or corresponding applications, but to avoid impractically high resolution at high data rates, the approach of using a floating-point analog-to-digital converter (FP-ADC) has been investigated. This approach de-links the dynamic range with the resolution, and a very wide dynamic range can be achieved by an ADC with a moderate resolution. LÄS MER
