Abstract
PURPOSE: To secure the quick and accurate measurement of the modulation degree through the arithmetic process and by holding the peak value, non-modulation level value and down-value from the modulation waveform.
CONSTITUTION: The RF signal is supplied to terminal 1, and the AF signal is drawn out through amplifier 2 and detection circuit 3. Switching circuit 5 functions to draw out components AWC of the RF signal and holds peak value A, non-modulation level C and down-value B respectively at holding circuits 6W8. Voltage A-C and C-B are generated through subtraction circuit 9 and 10, and are the calculated through division circuit 11 and 11' as shown in the diagram to be sent to indicator 13 as well as to be drawn out to output terminal 14 and 15
