摘要
The comparator output is gated with the serial output of a ring counter driven from a clock and used to insert eight flip flops one after the other. The flip flops are set, by the direct output of the counter, and the outputs are, in turn fed to the digital to analogue converter. The effect of this is that the first, or most significant flip flop set first, the corresponding output is produced by the converter and compared with the input signal. If the converter output is smaller than the input signal, the flip flop remains set. Otherwise it is unset. The second flip flop representing the next (less significant) bit is then set, and either unset or not according to the converter output, and so on until the whole signal is digitized.
