CS302 Current Final Term Paper Fall 2013 File 10


Today my paper


Q1.
 How many bytes will be there in 16K x 8 memory? (Marks 2)

Ans.
 A 16 K x 8 memory, stores 16K bytes or 16 x 1024 = 16384 bytes or 131072 bits.

Q2.
Draw state diagram of Moore machine.
Ans.

Q3.
Write down at least two applications of a shiftregister. Answer:- (Page 356) The two applications of the shift registers are 1. Serial to Parallel converter 2. Keyboard encoder



Draw the NOR based S-R Latch
Ans.
Q4.

Explain application of demultiplexer
Ans.
Demultiplexer is used to connect a single source to multiple destinations. One use of the Demultiplexer is at the output of the ALU circuit.

Q6.
3: Explain the next-state table with the help of a table for any sequential circuit? Answer:- (Page 306) Once the statdiagram of the sequential circuit is defined, a Next-State Table is derived which lists each present state and the corresponding next state. The next state is the state to which the sequential circuit switches when a clock transition occurs. Present State
 Next State

Q7.
Explain Programmable Logic Devices?
Ans.
Programmable Logic Devices are used in many applications to replace the Logic gates and MSI chips. PLDs save circuit space and reduce and save the cost of components in a Digital Circuit. PLDS consists of Arrays of AND gates and OR gates that can be programmed to perform specific functions.
