01․ In SSI, the number of gate circuits per chip is
02․ In MSI, the number of gate circuits per chip is
In MSI i.e. Medium Scale Integration number of gate circuits per chip is more than 10 but less than 100.
03․ In LSI, the number of gate circuits per chip is
In LSI i.e. Large Scale Intergration the number of gate circuits will be more than 100.
04․ In VLSI, the number of gate circuits per chip is
In VLSI, the number of gate circuits per chip is > 10000 but less than 1,00,000
05․ In ULSI, the number of gate circuits per chip is
In ULSI, the number of gate circuits per chip is >1,00,000 or > 1 million transistors.
06․ A device which converts decimal number into BCD form is called
Encoder is a combinational circuit which have many inputs and many outputs. Encoder is used to convert other codes to binary.
Such as, octal to binary, decimal to BCD and hexa decimal to binary.
07․ A device which converts BCD into octal is called
Decoder is a combinational circiut which have many inputs and many outputs. Decoder is used to convert binary to other codes.
Such as , binary to octal, binary to hexa decimal and BCD to decimal.
08․ A multiplexer is a
Multiplexer is a combinational circuit which have many data inputs and one output. Depending on select or control one of the data input is transfered to the output. Hence it is known as many to one circuit (N-to-1 device ).
09․ A demultiplexer is a
Demultiplexer is a simple circuit which have one input and many outputs. Demux is also called as one to many circuit (1-to-N device ) or data distributor.
10․ A device which converts 2421 code into 8421code is called a
2421 is weghted self complimented code and 8421 is weighted code. A device which converts 2421 code into 8421 code is called as a code converter.
