Design a binary counter capable of counting to at least 84, the number of students in this class. It's OK to have excess capacity. The counter should increment on the rising edge of an input signal we'll call COUNT. Another input called CLEAR should have the effect of setting the counter to zero if CLEAR = 1 when COUNT is asserted. Note that the counter should only change state, either to increment the count or clear to zero, on the rising edge of COUNT. You may use combinatorial logic gates and D flip flops. It is not necessary to display the output; just implement the counting engine.
A transmission line with no loss, with Z0= 60 ohms, is operated at 60MHz. The velocity on the line is c. The line is soldered to a ground connection at z=0. Find the input impedance into this line at z= -1.25 meters
Explain why the short-circuit method for determining the Thevenin resistance of a circuit cannot be applied if the circuit does not contain any independent current or voltage sources.
What is the symbol rate and what is the bandwidth occupied by the 16-QAM signal? The link must maintain a BER no higher than 10^-6. What is the minimum CNR in the receiver to meet this requirement?
Efficiency in a power transformer is 98.6% when loaded such that its core losses equal the copper losses. Calculate the per unit resistance of this transformer.
A battery is charged. The relationship between the charging current, i amperes and the time, t hours passed, is given by the formula:
Control Systems: Operation of a PID, Which one of the following statement regarding to operation of a PID is true?
A waveform generator is connected to an op-amp which has been setup as a voltage follower. The voltage follower is then loaded with a 50 Ohm resistor. What output impedance setting should the waveform generator use
calculate inductance of sensor for air gap of 1mm and 3mm?
An infinitely long line charge (Pl= 21 PI nC/m) lies along the Z-axis. An infinte area sheet charge PS= 3nC/m^2 lies in the X-Z plane at a distance Y =10 m. a) Using Gauss' law find the field E due to the line charge.
