design a decade counter which counts in the sequence:0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 0000a)use D flip-flopsb)use J-K flip flopsc)use S-R flip flopsd)use T flip-flopse)draw a complete state diagram for the counter of (b) showing what happens when the counter is started in each of the unused states
When a 100-k load is connected to a signal source, the output voltage is 30 mV. If a 10- k resistor is used to load the same signal source, the output voltage is observed to be 10 mV. Find the corresponding Thevenin voltage, Norton current
Three identical single phase transformers, each rated at 100KVA, 7KV/3.5KV, are connected as a three phase transformer bank. The high-voltage side of the transformer is connected in delta and the low-voltage side is connected in wye.
In a circuit, a resistor is only element that has resistance. The generator voltage varies in time, where the amplitude of e max= 1.2 volt and emf freq.= 0.5 Hz , which the max current is equal to the max current when the freq. of emf = 3.0 Hz,
Draw the circuit daigram for the twisted - tail ( Jonhson) counter consisting of 4 Flip flops (A,B,C,D) with the following excitations: Da='Qe, Db=Qa,Dc=Qb,De=Qc.Assume the flip flop are cleared intially .
A signal source produces a 4 volt peak-to-peak sinusoid and has a source resistance of 100 ohms. We wish to drive a grounded 10 ohm load to at least 2 volts peak-to-peak with this source. The load cannot tolerate DC. Your amplifier should not burn..
1) Modern technology has produced a small 1.5-volt alkaline battery with a nominal stored energy of 150 joules. For how many days will it power a calulator that draws a 2-mA current 2)The current entering the positive terminal of an element is
Determine which of the machines with the following specifications is realizable with a finite number of states. 1) A machine is to produce an output of 1 whenever the number of 1's in the input sequence exceeds the number of 0's.
A block error detecting code has a minimum distance of three. How many errors can this code detect and how many can it correct
Construct a sequential circuit with two data inputs, A and B and two data outputs X and Y whose sequential behavior is as follows: the machine accepts data on the two input lines synchronously with the clock.
A 1-uF capacitance is in parallel with the series combination of a 6-uF capacitance and a 3-uF capacitance. Sketch the circuit diagram and determine the equivalent capacitance of the combination.
The phasor voltage Vab in the circuit is 480 /0° V (rms) when no external load is connected to terminals a,b. When a load having an impedance of 100 j0 Ω is connected across a,b, the value of Vab is 252.9822 /-18.3449° V (rms).
When the amplifier is operating with a bandwidth first of 10MHz, find? 1) The RMS input noise power level? 2) The audio output power level? 3) The RMS output noise power level?
