certain amount of time to propagate from input to the output. This interval of time is defined as the propagation delay of the gate, It is expressed in nanoseconds. 33. down fan in and fan out of a standard TTL IC. (May 2006) Solution: Fan out of a standard TTL IC is 10 34. What is the advantage of using schottky TTL gate? (May 2007) Solution: The advantage of schottky transistor is it decreases the propagation delay without a sacrifice of power dissipation Draw two CMOS NOR gate. (Nov 2007) Solution: Define Fan-out and fan in of a Digital IC. (Nov 2004/2005/2007/2011) Solution: Fan-out is defined as the maximum number of input of the same IC family that the gate can drive maintaining its output level within the specified limits. Fan in is defined as the total number of inputs to a logic gate. (Eg) an inverter has a fan-in of 1. 37. Implement the following using PROM = (EI April’10) F ∑m(0,1,2) . Define address space and memory space? (EI Dec 13) In virtual memory, the user gives a larger address called virtual address. A set of such addresses is called address space. The equivalent main memory address generated in the location of physical address. A set of such location is called the memory space
