An XY flip flop whose characteristic table is given below is to be implemented using a T flip flop
This can be done by making
Which of the following ADC has a fixed conversion time?
The sequence (Q_{2} Q_{1}) when successive clock pulses are applied
A number P represented in signed binary 2’s complement form is 1001101. Another number Q_{1} represented in signed binary 2’s complement form is 11010111. If Q is subtracted from P, the result expressed in signed binary 2’s complement form
Figure shows the initial content of a 6 bit SIPO register with each clock pulse output of gate G_{1} is pushed in the left most stage. What will be the content of the register after 9th clock pulse?
The function y (A, B, C) implemented by the circuit shown is
In the latch circuit shown if A = 1, B = 0 is applied, the corresponding stable outputs are
A digital bit is to be transmitted from point P to point Q by delaying it through a SISO register of 8 bit as shown. If the clock frequency used is 4 MHz, the delay created by the register is
The resistance corresponding to LSB in a weighted resistor 5 bit DAC i s 64 k?, then the resistor corresponding to MSB is
The output of a 6bit DAC for the digital input of 1001000 is 300 volts. What will be the DAC output for digital input 1101010 approximately
In the circuit shown in figure, to make Low, what must be conditions at A and B
The counting sequence (Q_{1} Q_{2}) when clock pulses are applied
The binary equivalent of the gray code (1011100 11)_{G}
An analog input of 4.20 Volt is to be converted into digital form using counter type ADC. The digital equivalent will be [Taking threshold voltage of comparator as one tenth of DAC resolution)
The present state of a JK flip flop was 0. After one clock pulse, it was found to be 0. What possible inputs
may be applied?
Figure below shows a free running oscillation.
Assuming propagation delay of each inverter 10 μs, the output frequency f_{0} is
(a) (b)
(c) (d)
