Abstract :
This paper deals with considerations that go into the design of modulation equipment for a single-sideband radiotelephone transmitter in which filters are used for sideband suppression. Balance requirements, frequency stability, the choice of intermediate frequencies, and methods of avoiding transmission of spurious frequencies are among the factors which are discussed.
