The basic functionality of a D flip-flop can be implemented by a JK flip flop simply by connecting the input signal D to the JK flip-flop's J input and the D to the K input.
Draw a timing waveform for the clock, input D, and outputs Qpos, Qneg, and Qms that illustrates the differences in input/output behavior of a positive edge-triggered D flip-flop, negative edge-triggered D flip-flop, and master/slave flip-flop (implemented from a JK master/slave flip-flop as described in the text). Include some transitions on D while the clock is asserted.
Maximum value of frequency deviation is fixed at 75 kHz for commercial broadcasting by radio. Modulation frequency W = 15 kHz, then find the transmission bandwidth of signal and deviation ratio.
Build and test the operational amplifier summing circuit you designed for the Prelab using 741-type op-amps. Use VA = 2 V and VB = 3 V with power supply rails of ±18 V. Ask your lab instructor to give the correct pin-out of the 741 if necessary.
A modulating signal consists of two sinusoidal components: 1 kHz and 3 kHz. The transmitter carrier frequency is 80 kHz. If the signal is applied to an ideal DSB transmitter, indicate the output frequencies (in kHz).
A spacecraft uses two ground-based computers and one on-board computer to control the thrusters used to make course corrections. There is also a manual override control that will switch control of the thrusters directly to the onboard computer in ..
A 250hp, 500v dc shunt motor draws a nominal field current of 5A under rated load. The resistance is 90ohms. Calculate the ohmic value and power of the series resistor needed so that the field current drops to 4.5A
An Alternator is found to have its terminal voltage on load condition more than that on no load. What is the nature of the load connected
A student project is required to be portable and hand held. It requires 6 V DC power at a current of 150 mA. The batteries for the power supply must last for a minimum of 7 hours of continuous operation.
One step in decoding a simple code without knowing the coding scheme , involves counting the number of occurrences of each character. Then, knowing that the most common letter in English is "e" the letter that occurs most commonly
A solid sphere with a radius of 75 mm rolls (without slipping) down an inclined plane that is 5 m long. What is the angular velocity of the sphere at the bottom of the plane if it requires 10 seconds for it to reach the bottom
Where (in the sequence of subsystems within a communication system) does the line encoder used? Draw a block diagram. Write a sentence or two on what is in the other boxes. What are the two broad parameters associated with an efficient line encoder..
Derive a minimal state table for an FSM that act as four bit parity generator. For every four bits that are observed on the input w during four consecutive clock cycles, the FSM generates the parity bit p = 1
The average number of vacation days per year offered by different US companies is skewed to the right. A random sample of 60 companies showed the mean number of vacation days was 22, and the standard deviation was 9 days.
