Abstract

Correction of differences between two analog to digital converters (ADCs) in broadband intermediate frequency conversion. By stimulating a two-ADC system with a known input, the impulse response of the system is derived, and from that impulse response a finite impulse response filter is derived which corrects for mismatches between the ADCs.
