Q6.An 8255 chip is interfaced to an 8085 microprocessor system as an I/O mapped
I/O as show in the figure. The address lines A0 and A1 of the 8085 are used
by the 8255 chip to decode internally its thee ports and the Control register.
The address lines A3 to A as well as the signal are used for address
decoding. The range of addresses for which the 8255 chip would get selected is
Q10.If the Laplace transform of a signal then its final value is
Answer : Option DExplaination / Solution:
Final value theorem is applicable only when all poles of system lies in left half of S -plane. Here s = 1 is right s −plane pole. Thus it is unbounded.
