1. Design a circuit that has 4 inputs, WXYZ, and two outputs, f and g, where W is the most and Z is the least significant bit. The output f is asserted whenever the two-bit number WX is greater than the two-bit number YZ. The output g is asserted whenever the 4-bit number represented by WXYZ, is evenly divisible by 4. Design this circuit using gates. Sketch the SOP realization using NANDs only. Sketch the POS realization using NORs only. (You should treat each output separately and determine the truth table for each.)(MSB) WX fY g(LSB) Z
2. Repeat Problem 1 using 8-to-1 MUXes and a minimal amount of gate logic. Sketch the resulting circuit indicating how the MUXes are to be connected to generate the outputs, f and g.
3. Repeat Problem 1 using a 4-to-16 decoder and a minimal amount of gate logic.
Using many resistors and the DMM, try to determine what digits each colour band represents. Briefly explain your method and your findings in the space below.
An AC synchronous motor operates at 1200 rpm on a 60 hz, 240 Vrms supply. The supply is changed to 50 hz, 240 Vrms, What is the mechanical rotational velocity when the motor reaches steady state
determine the current drawn from a 3 phase 220 V line by a 3 phase 15kW motor operating at half load, 85% efficiency and .8 pf lagging. Find the values of real and reactive power drawn from the line.
A 60-Hz, single-phase transmission line has a length of 80 miles. Its shunt conductance (G) is 3.4A1011 S/mile, resistance (R) is 0.1 OHMS/mile, capacitance (C) is 16 pF/mile, and inductance (L) is 0.56 mH/mile.
For the local oscillator you selected, what transmission frequencies could cause interference to the satellite system and how could the interference be avoided? Show a diagram.
Consider an 8-user CDMA system. The data vector of all users is given by [1,1,1,1,-1,-1,-1,1]. Find the total transmit signal.
A given low pass filter has a cutoff frequency fc and a sample frequency fs. The sampling period is T = 1/fs. In implementing the filter it is essential that the evaluation of the difference equation be completed in less.
A coil having 1000 turns is wrapped on ferromagnetic core constructed of sheet steel. The core has a cross-sectional area of 0.0009 m^2 and an average flux path of 30.0 cm. The core also has a length of 2 mm. The flux density in the core and airga..
A radar transmits a monotone pulse of 5-s duration. Suppose the radar were redesigned so that the same pulse envelope is frequency modulated with linear FM over 100 MHz. (a) What is the possible new range resolution
Water is the working fluid in a vapor power cycle with reheat, superheat and reheat. Superheated steam enters the first turbine stage at 8 MPa, 480 C and expands to 0.7 MPa
An otherwise-ideal op amp, known to have an open loop gain of 10^4 V/V , is measured in a circuit to have an output voltage of -3 V. While it would be difficult to measure, what would you expect the voltage from the negative terminal
In and Th are inputs and Out is the result. All parameters are 8-bit unsigned integers. A typical calling shows that the two inputs, In and Th, are passed on the stack and the return parameter Out, is returned in RegB.
