Digital-electronics Questions Set 150:
The number of unused states in a 4-bit Johnson counter is
Solution:
For 1:8 demultiplexer in figure, determine the number of select lines.
Solution:
What is the dual of the expression A+[B+(AC)]+D?
Solution:
If we apply A=B=C=0 and A=B=1, C=0 for the Boolean equation (A.B)'+C. Find the Corresponding outputs.
Solution:
If A x-or B = C, B x-or C = A & A x-or C = B, then the value of [(A x-or B x-or C) x-or D] x-or [(A x-nor B) x-nor C] will be
Solution:
The implicants that will definitely occur in the final Boolean expression are called
Solution:
Jason was using an asynchronous counter. To remove the internal propagation delay, which type of counter should he configure?
Solution:
A 10 MHz clock frequency is applied to a cascaded counter consisting of a modulus-5 counter, a modulus-8 counter, and two modulus-10 counters. The lowest output frequency possible is
Solution:
A divide by 6 counter circuit can be designed using one AND gate and three D-flip flops. The outputs of the 2nd and 3rd flip flops are connected as the input of the AND gate which is then connected to the RESET pins of each flip flops.
Solution:
The reverse saturation current of a Germanium (Ge) transistor is 2 μA at a room temperature of 25°C. The reverse saturation current increases by a factor of 2 for every 10°C increase in temperature. Find the reverse saturation current of the transistor at a temperature of 75°C.
