High-frequency receiver, particularly for a nuclear magnetic resonance apparatus |
摘要 |
A high-frequency receiver with an analog input part has at least one analog mixer stage, this mixer stage being operable with an injection frequency, and a following digitalization stage. The digitalization stage includes an analog-to-digital converter for digitalizing a signal emitted by the analog input part with a sampling rate prescribed by a sampling frequency. A signal generator for generating the injection frequency or the sampling frequency is connected to the mixer stage and to the analog-to-digital converter, this signal generator generating the injection frequency or the sampling frequency only as a whole number multiple of a basic frequency.
