A  line code  is the code used for data transmission of a digital signal over a transmission line. This process of coding is chosen so as to avoid overlap and distortion of signal such as inter-symbol interference. Properties of Line Coding Following are the properties of line coding − As the coding is done to make more bits transmit on a single signal, the bandwidth used is much reduced. For a given bandwidth, t...

                                                                                          Name of Experiment :- Experimental study of Delta Modulation and signal reconstruction The sampling rate of a signal should be higher than the Nyquist rate, to achieve better sampling. If this sampling interval in Differential PCM is reduced considerably, the sampleto-sample amplitude difference is very small, as if the difference is  1-bit quantization , then the step-size will be very small i.e.,  Δ   d e l t a d e l t a . Delta Modulation The type of modulation, where the sampling rate is much higher and in which the stepsize after quantization is of a smaller value  Δ , such a modulation is termed as  delta modulation . Delta Modulator The Delta Mod...
