Abstract
By the use of two additional mixing stages (21, 26) it is possible to replace the 2H glass delay line (operating at approximately 4.43 MHz) used in the known modulators by, for example, a charge-coupled device CCD (8) (which operates at approximately 625 kHz), enabling the total storage capacity required to be reduced in comparison with the situation in which the glass delay line is replaced directly by a CCD (operating at 4.43 MHz).
