Abstract :
SINCE the advent of the varistor modulator in carrier communication equipment about 20 years ago, much has been written on the theoretical nature of the modulation processes involved. Very little has been written with regard to the practical problems in modulator use encountered by the designer. This paper will stress the practical rather than the theoretical.
