Comment on Send Your Problem by Nir Dahan

Parbir,

this is easily solved by looking at all the cases.
the LSB of the result (in BCD) is either 0000 (when the input LSB is 0) or 0101 (when the input LSB is 1).
the MSB of the result is a 0 followed by the 3 MSBs of the input.

to sum up the solution, given the input is [3:0], is:
{”0″,input(3),input(2),input(1)} , {”0″,input(0),”0″,input(0)}

If you still have difficulties with it let me know. we can correspond via email.
it is a nice interview question and I will post it with its solution in the future.

Design a combinational circuit, that multiplies an input decimal digit represented in BCD by 5.
The output is to be represented in BCD. Show that the outputs can be obtained from the input lines without using any logic gates.

sometimes, we use the “mean time to failure” to measure the performance of a synchronizer. I would be happy to know your opinion about this. thank you.
