Multiplexes 4 channels
Each frame has 8 bits per channel plus one framing bit
Frame size= 4*8 + 1 = 33 bits per frame
For voice each channel contains one word of digitized data (PCM, 8000 samples per sec)
Data rate 8000x33 = 0.264 Mbps
Included in this industry are digital computers, analog computers, and hybrid digital/analog computers.
Digital computers work with exact discretely coded representations of numbers.Analog computers work with approximate continuous representations of numbers.Hybrid computers are computers that are part digital part analog.I have used all three types, each has advantages.
True
built with the same level of technology, analog computers are always faster but less accurate than digital computers. however as little significant work on analog computers has been done since the 1980s, they currently significantly lag behind digital computers in speed.
No, your desktop computer is a digital computer as are virtually all modern computers.
No, a laptop is a kind of digital computer. Analogue computers used operational amplifiers in feedback loops to simulate dynamic systems such as aircraft. They began to be replaced by digital computers in the 1960s
The microchip.
Digital computers are classified based on their size into microcomputers, minicomputers and mainframe computers. Other types include supercomputers, network computers, laptops, palmtops and PDAs.
All computers are digital. *Analogue
There is a great scope in computer engineering. In Computer engineering, students study the design of digital hardware and software systems including communications systems, computers and devices that uses computers.
The odd one out is "digital computer." While microcomputers, mini computers, and supercomputers refer to specific categories of computer systems based on their size and processing power, "digital computer" is a broader term that encompasses all types of computers that process data in a digital format. Thus, it doesn't fit into the distinct classifications represented by the other three terms.
a. computers are used in all digital technologies.
