Method and apparatus for analog-to-digital conversion

摘要: The present invention eliminates the need for an anti-aliasing filter in a receiver that employs analog-to-digital converter. By maintaining predetermined relationship between local oscillator frequency and sampling of converter, aliasing would normally occur desired pass band is avoided. More specifically, periodic signal provided to mixer integer multiple half rate In preferred, non-limiting example embodiment, converter F ?ADC#191 F?LO#191 are related by following: F?LO=n#191*F?ADC#191/2, where n any positive integer.
