Abstract
A system including a sample-and-hold circuit for receiving a plurality of analog input signals; an analog-to-digital converter for converting each of the analog inputs to a digital signal; and a processor configured for implementing fractional delay recovery for the analog-to-digital converter. In some embodiments, the fractional delay recovery includes converting each of the plurality of analog input signals to a digital version in the predetermined order; upsampling each digital version in the predetermined order; digitally filtering each upsampled value in the predetermined order; and downsampling each filtered value in the predetermined order.
