Abstract:
A radio receiver, in which a input power level detected by an analog-to-digital converter for digitally converting a voltage from a voltage converter for converting a signal received from an antenna is displayed on a input power level display, comprising:a memory circuit for storing digital values AAD, BAD and CAD from the analog-to-digital converter when electric fields A, B and C, respectively, are received from the antenna; an operational circuit for obtaining a non-linearity corrected input power level conversion table by calculating input power levels from the digital values; a table memory circuit for storing the input power level conversion table; and a controller for displaying the input power level at the time of reception of each electric field by reading out the input power level conversion table in the table memory circuit, wherein the electric field C is a saturation starting point in the receiver circuit at high input power level electric field input time.
