Transmit-receive system and transmission method, in particular for a mobile telephone |
摘要 |
A transmit-receive system includes a phase-locked loop and a translation frequency loop. To bring about frequency hops, the frequencies in the two loops are varied with large increments in opposite directions. It is shown that the noise caused by the frequency division in the loops is thereby reduced.
