    Abstract: A delta modulator converts an analog signal into a PCM code and also provides a corresponding delta modulated signal. The modulator includes a bidirectional counter in its feedback path which counter stores a code corresponding to the sequence of sampled delta modulated signals. The stored code is converted into an analog feedback signal and a PCM code is derived from the counter outputs.

    Abstract translation: Δ调制器将模拟信号转换成PCM码并且还提供相应的增量调制信号。 调制器包括在其反馈路径中的双向计数器,其计数器存储对应于采样的delta调制信号的序列的代码。 将存储的代码转换为模拟反馈信号,并从计数器输出中导出PCM代码。
