Advanced Digital Signal Processing and Noise Reduction, Second Edition. Saeed V. 10 Thermal Noise Shot Noise Electromagnetic Noise Channel Distortions Modelling Noise oise can be defined as an unwanted signal that interferes with the communication or measurement of another signal. A noise itself is a signal that conveys information regarding the source of the noise.

At the transmitter, speech is segmented into blocks of about 30 ms long during which speech parameters can be assumed to be stationary. Each block of speech samples is analysed to extract and transmit a set of excitation and filter parameters that can be used to synthesis the speech. At the receiver, the model parameters and the excitation are used to reconstruct the speech. 11. The aim of transformation is to convert the signal into a form where it lends itself to a more convenient and useful interpretation and manipulation.

4 Time and frequency sketches of: (a) an ideal impulse, (b) and (c) shortduration pulses. 5 Illustration of variations of the impulse response of a non-linear system with the increasing amplitude of the impulse. 5 illustrates some examples of impulsive noise, typical of those observed on an old gramophone recording. In this case, the communication channel is the playback system, and may be assumed to be time-invariant. The figure also shows some variations of the channel characteristics with the amplitude of impulsive noise.
