What is Adaptive Delta Modulation?

Adaptive delta modulation offers extremely high performance. This technique decreases the need for correction circuits in radio design and error detection. Dynamic range is high since the variable step size covers a large range of values. Slope overload error and granular error are not seen. Slope error is reduced.

What is ADM in Delta Modulation?

ADM quantizes the difference between the value of the current sample and the predicted value of the next sample. It uses a variable step height to predict the next values, for the faithful reproduction of the fast varying values.

How do you modulate a signal in Matlab?

y = modulate( x , fc , fs ) modulates the real message signal x with a carrier frequency fc and sample rate fs . If x is a matrix, the modulated signal is computed independently for each column and stored in the corresponding column of y . [ y , t ] = modulate( x , fc , fs ) also returns the internal time vector t .
