This module consists of a board for studying Delta, Adaptive Delta and Delta/Sigma Modulation.

Delta modulation transforms an analog signal into a stream of digital data, transmitting one bit every time the analog signal is sampled.

This modulation has some drawbacks depending on various parameters, for example the variation slope of the analog signal to be transmitted at the sampling frequency. Due to this there are different types of delta modulation.

This module allows to show the three main deltas: Delta modulation. Adaptive-delta modulation. Sigma-delta modulation.

This allows the study of the parameters: sampling frequency, sampling step size, and analog input signal frequency and amplitude.

Transmitter and receiver in-built integrators enabling selection of four different gains using switches or automatic gain variation.

Includes four input signals at 250 Hz, 500 Hz, 1 KHz, and 2 KHz, and also a direct current signal, all of them of variable amplitude and potentiometer, as well as the possibility of introducing an external signal.
