First of all analog Voice has a frequency range upto 3400Hz.
In order to convert the analog voice to a digital we use PCM (analog / digital
conversion). The voice signals will need to subjected by a process
known as sampling, quantisation and encoding (binary level).
As speech is 3400Hz the sampling rate is 8000Hz. The encoding generates
8 bits of information.
A TDM E1.0 system has 32 Time Slots. Time slot 16 is used for signalling (by
convention) and Time Slot 0 (zero) is used for synchronisation and Frame alignment.
I NEED TO SHARE THIS QUESTION WITH ALL OF YOU AND SEE IF WE CAN GET A ANSWER:” AN AMPLIFIER WITH 3dB GAIN IS FED WITH A 6WATT INPUT SIGNAL. WHAT IS THE OUTPUT POWER IN WATTS?”
It is purely a comparison between two levels, and on its own it cannot be used to measure an absolute level. As a result of this the quantities of dBm and dBW are used:-
dBm – This is a power expressed in decibels relative to one milliwatt.
dBW – This is a power expressed in decibels relative to one watt.
