Advances in analog converter technology now allow IF sampling which can greatly simplify receiver design. Advances in digital integrated circuits also advance the state of the art in terms of digital tuning and filtering. Together these two chips can replace many of the cumbersome stages of a traditional analog receiver with predictable and reliable performance. The superheterodyne recei……
