Delta modulation - Wikipedia
Delta modulation (DM or Δ-modulation) is an analog-to-digital and digital-to-analog signal conversion technique used for transmission of voice information where quality is not of primary importance.
What is Delta Modulation? Definition, Block diagram for Delta ...
A technique that converts or encodes message signal into a binary bit stream is known as delta modulation. As only 1 bit is used to encode 1 voltage level thus, the technique allows transmission of only 1 bit per sample.
Digital Communication - Delta Modulation
Delta Modulation is a simplified form of DPCM technique, also viewed as 1-bit DPCM scheme. As the sampling interval is reduced, the signal correlation will be higher. The Delta Modulator comprises of a 1-bit quantizer and a delay circuit along with two summer circuits. Following is the block diagram of a delta modulator.

Delta modulation (DM) is an easy way of DPCM. In this technique, the difference between consecutive signal samples is encoded into n-bit data streams. In DM, the data which is to be transmitted is minimized to a 1-bit data stream.
Delta Modulation- Its Block Diagram and Applications - ElProCus
Delta modulation is a scheme to permit the use of a simple quantizing strategy for constructing the encoded signals which are over-sampled purposely, to increase the correlation between adjacent samples of the signal, as seen in Differential pulse code modulation method.
Delta Modulation - an overview | ScienceDirect Topics
Delta modulation (DM) is a scheme in which an oversampled baseband signal is approximated using a staircase function, with the difference between the input and the approximation quantized into only two levels. It is a simplified version of differential pulse-code modulation (DPCM), using a one-bit quantizer and a single delay element.
