Abstract

PURPOSE: To convert directly FM signals to AM signals by a converter, where FM signals and an AM carrier wave are inputed to obtain sum (difference) frequency components of respective signals, and a conveter where the components above and FM signals are inputted to obtain difference (sum) frequency components.
CONSTITUTION: Signals of two frequencies are inputted to first and second frequency converters 5 and 6, and they output signals of sum (difference) frequency components or difference frequency components. FM input signals and AM carrier signals are inputted to converter 5 to output signals of sum (difference) frequency components. These sum (differnce) frequency signals are supplied to converter 6 through slope filter 7 having a passage characteristic of an amplitude level proportional to the frequency. Then, the first conveter is formed by converter 5 and slope filter 7. Second converter 6 outputs signals (AM signals) of difference (sum) frequency components between two input signals.
