To achieve high signal-to-noise ratio, delta modulation must use over sampling techniques, that is, the analog signal is sampled at a rate several times higher than the Nyquist’s rate. Only the change of information is sent, that is, only an increase or decrease of the signal amplitude from the previous sample is sent whereas a no-change condition causes the modulated signal to remain at the same 0 or 1 state of the previous sample. The decision process for establishing the state of successive bits is determined by this comparison 4. Each segment of the approximated signal is compared to the original analog Wave to determine the increase or decrease in relative amplitude.

The analog signal is approximated with a series of segments 2. In delta modulation, the transmitted data is reduced to a 1-bit data stream. DM is the simplest form of differential pulse-code modulation (DPCM) where the difference between successive samples is encoded into n-bit data streams. Theory of Delta Modulation 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. levelįour integrator gain settings Normal, X 2, X 4, X 8įourth order Butterworth (Cut Off Frequency- 4.8 KHz)

A switch is provided for the selection of manual or automatic gain control. Automatic gain adjustment is done by control circuit. Manual gain control in both transmitter and receiver is done by switches labeled A & B. Integrators in transmitter and receiver blocks are provided with manual and automatic gain control. Transmitter and receiver clocks are switch selectable and can also be observed at test points 10 and 11 respectively. These frequencies can be observed at test points 6, 7, 8 and 9 respectively. Six sampling clock frequencies of 50, 100, 200 and 400 KHz are provided on board. Various test points on the trainer make user understand, the complete process that takes place for the Delta modulation and demodulation process. The trainer requires ☑2V and ±5V (200mA) dc signal which can be obtained from Scientech Power Supply Model AD-01 Synchronized & Adjustable Amplitude Sine Wave Generators of 1, 2, 3 & 4 KHz and separate adjustable D.C. It covers the concepts of delta modulation demodulation, slope overloading, adaptive delta modulation demodulation, sigma delta modulation demodulation and amplitude overloading. Introduction The ST2155 Delta Modulation & Demodulation Trainer demonstrates the delta, adaptive delta and sigma delta modulation and demodulation schemes.
