The utilization of the inactivity periods that always exist in both transmission directions of a telephone conversation. The interpolation is used in order to increase the efficiency and lower the cost of long distance links. Analog signals with quiescent periods or long vowels are compressed, for example by time assignment speech interpolation, transmitted, and expanded by inverse compression(expansion) at the receiving end. This principle... is now being developed for digital speech [and] when pulse code modulation is used, the process is known as digital speech interpolation.  1, record 5, English, - analog%20speech%20interpolation

HDTV signals contain over 700 lines of resolution compared to the 525 lines of resolution that analog provides. HDTV also has a wider width to height of the screen for a true theater-like experience. The images are digitized and compressed before signal transmission to enable the tremendous quantity of information to pass through easily. The signals are then decompressed when they reach the television. The result is a clear, crisp picture that transcends any other picture formats.  1, record 9, English, - HDTV

The representation of a general pulse transmission system is given in Figure 8. 1. Here, the information input to the system is encoded in some sense.... This encoded signal drives the modulator, which maps the pulse sequence into an analog wave suitable for transmission over the channel.... At the receiving end, the demodulator maps the received analog waveform into a pulse sequence that is a "best guess" of the sequence transmitted. The decoder operates on the binary sequence to extract the information originally impressed on the encoder. The overall objective is to transfer the information from the input to the output within some a priori specified low error rate, where the error rate is the average number of disagreements per unit of time between the inputs and the outputs.  1, record 19, English, - pulse%20transmission%20system
