1. Write the full equations to light the bottom segment of a 7-segment display. INLCUDE the hexadecimal digits too ( b, c, d, and E ). Then simplify the equations using a k-map and draw the final circuit.
2. Draw a CMOS circuit for an S-R flip-flop.
3. Explain the basic operation of a CMOS transmission gate and compare it to a tri-state buffer. There is one important difference, make sure to explicitly discuss that difference.
4. Design a 3-bit counter using D flip-flops to cycle through the following sequence: 010, 101, 110, 001. Make sure the counter is self-starting.
A measurement system uses an 8-bit A/D converter as output for itssignal in a range of 0 to 10 volts. What is the resolution for this measurement system If a7-bit A/D converter or a 9-bit A/D converter to be used, what is the resolution for the sys..
TDMA has 416 frequencies in one of the cellular license bands. If a cellular operator designs a network with a 5/15 reuse pattern, how many frequencies per cell (sector) can be supported? ( ignore control channels)
If the per-phase line loss in a 60-km-long transmission line is not to exceed 60kW while it is delivering 100A per phase, compute the required conductor diameter, if the resistivity of the conductor material is 1.72*10^-8 Ohm-meters.
A synchronous generator has a rated outputof 250MVA, rated voltage of 13.8kV, a rated power factor of 0.85lagging and a synchronous speed of 1800rpm. what is the complex power output when operating at rated conditions
Consider the waveform equation: a. What is the frequency of the waveform (in Hz) b. What is the voltage Vx at a time t = 1.5 ms c. What is the voltage Vx at a time t = 3 ms d. What is the voltage Vx at a time t = 4.5 ms
Determine the maximum raw instantaneous data rate that can be provided to a single user in EDGE, assuming that a single time slot on a single GSM channel is available.
A 150 KVAR capacitor is connected across the line in Problem 1. (a) Sketch and label the power triangle for the capacitor. (b) Sketch and label the power triangle for the combined loads (capacitor and motor).
An amplifier operating from +/- 12 V power supplies has alinear transfer characteristic except for output saturationat+/- 11.4 V. a) The peak-to-peak value of the largest sinusoidal wave thatcanbe applied at the amplifier input without output dist..
The current in a circuit element is i(t) = 4 sin 3t A when t ≥ 0 and i(t) = 0 when t Determine the total charge that has entered a circuit element for t ≥ 0.
Design a power supply using a 24V, center-tapped transformer to supply 12V at 500mA, -12V at 100mA and 5V at 250mA. What is the minimum current rating of the transformer
in the hopkinsons test the power is supplied to overcome the losses in the same way is there any analogous in ac
A 3-Phase stepping motor is to be used to drive a linear axis for a robot. The motor output shaft will be connected to a screw thread with a screw pitch of 5 mm. We want to be able to have a spatial control of at least 0.1 mm.
