ABSTRACT:
A volume control or amplitude varying system for digital signals includes a cascade connection of a coarse multiplier/divider for changing the values of digital signals in 6 db steps and a fine multiplier/divider for changing the values of digital values logarithmically in substantially equal steps of less than 6 db per step. The coarse multiplier/divider selectively multiplies the digital signal by powers of 2. The fine multiplier/divider multiplies the digital signal by predetermined values, an ascending/descending sequence of which form a substantially logarithmic sequence. Both serial-bit and parallel-bit embodiments are described.
