Equalization is performed to correct for misalignment of the frequency responses of the sub-ADCs in the composite ADC. In a form, ADC output signals are applied to a mixer array to frequency down-shift the digital form of the input signal, followed by digital filtering to effect convolutions of portions of the digital form of the input signal with a set of convolution coefficients determined so that the net processing is mathematically equivalent to down conversion with equalization. In another form, the ADC output signals are directly applied to a digital filter to effect both frequency down-shifting and convolutions, with filter coefficients determined so that the net processing is mathematically equivalent to down conversion with equalization."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital down converter with equalization","description":"A digital down converter with equalization includes a composite ADC that performs demodulation of a received analog signal, converting the signal into in phase baseband signal and quadrature baseband ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9634679","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
