Abstract: 1360943 D/A converter MARCONI CO Ltd 16 Jan 1973 [24 Feb 1972] 8562/72 Heading G4H A D/A converter for use as a P.C.M. decoder is of the kind which obeys a segmented D/A conversion law, i.e. the plot of output voltage of the converter against input digital words consists of a number of joined straight lines of increasing gradient and length away from the origin, includes means for receiving the input digital code and for examining it to determine on which one of the straight-line segments the analog value will lie, means for generating a linearly increasing signal and means for arranging that the rate of linear increase corresponds to the slope of the one straight-line segment, the rate of increase being maintained constant until the desired analog signal value is reached. As shown (Fig. 3) an 8-bit binary word is received at register 1, the m.s.b. being indicative of the required polarity and is taken to a selector 10 while the next 3 m.s.b.'s. indicative of the segment are taken to a decoder 13 where one or more signals emerge to activate one or more of constant current generators 14-17 to linearly charge capacitor 18 at a rate determined by the 3-bit word and equal to the segment slope in which the output is required. The four l.s.b's indicative of the position of the output within the segment are taken to a comparator 23 for comparison with the output of a four-bit binary counter 24 which is incremented via a clock oscillator 26 and the counting operation may be modified by a 16 clock pulse delay 29 and a divide by 2 circuit 27 if required, which circuits may be selectively brought in under the control of units 32, 33 which are controlled by the 3 m.s.b. word. In operation as shown in Fig. 2, 8 segments may be provided, each pair (1), (2) &c. having the same gradient. A start circuit 28 simultaneously commences the charging of capacitor 18 at the desired rate and enables the clock oscillator. It is seen that segments (2), (3), (5), (7) require 16 clock pulses to bring the value of the voltage at 18 to the foot of the segment and hence the clock stream is delayed by 16 pulses for all these segments so that counting commences only when the output voltage is at the foot of the segment. Also segments (4), (6), (8) are twice as long and require 32 pulse periods to bring the output value to the foot of each one, and in these instances the frequency divider is also switched in.
