Abstract

PURPOSE:To eliminate non-linearity dependent upon omission of the number of digits by using a micro processor to switch quantization units in the transmitter- receiver which has a digital frequency set function having plural quantization units. CONSTITUTION:Frequency data is stored in a RAM of processing circuit 13 by input signals from keyboard switch 14. When quantization unit selector switch 15 is switched to another quantization unit, omission of display data is performed with the quantization unit by processing circuit 13, and the result is outputted to display circuit 16. Omission of data signals to a PLL circuit may be omitted. Omission of display data is performed by input signals from quantization unit selector switch 15 to switch display data with quantization units, so that quantization units can be detected.
