, and in order to provide communication of sound, text and video signals which are passed on through any existing high frequency analogue signal medium, it is according to the invention suggested that the television communication system comprises a further system providing digital one-way and/or ...
This information transmission system for speech, music, text, images and data has a basic telecommunications network (I), in particular for analog transmission, and an additional digital overlay network (II). The two networks are interconnected between their terminating exchanges (6, 7, 9, 11) ...
analogue-to-digital converter (ADC) converts whole decimal numbers between 0 and 23into digital numbers.State(i) the minimum number of bits in each digital number,number of bits =[1](ii) the digital number representing decimal 13..[1](c)An analogue signal is digitised before transmission. ...
There are however drawbacks to analogue signals, which have resulted in most of our modern electronic systems being digital. One drawback of analogue signals is that they are very susceptible to transmission errors; meaning that the the analogue signal arriving at the receiver is fairly guaranteed ...
The network connection system for a central exchange is able to multiplex both analogue and digital signals as may appear in a mixed system using 2/4 lines. The network uses a primary multiplexer and demultiplexer connected to both transmission and reception lines and also via a bus to a secon...
