1) How can you use a 2-input XOR gate to function as a 1-bit buffer/inverter? Draw the logic diagram. Show the logic connections for the control and data input lines.
2) Draw the logic circuit for each of the following. For each gate, determine EVEN or ODD parity and find the output for the given input data:
a) 4-input XOR, input data=1001
b) 5-input XOR, input data-10010
c) 6-input XOR, input data=101001
d) 7-input XNOR, input data=1011011
Capacity, Data and Transfer Rates, Access Time of Disk Drive, A hard disk drive has 10 disks and 18 surfaces available for recording. Each surface is composed of 200 concentric tracks and the disks rotate at 7200 r.p.m.

one question: During each cycle, the velocity v (in mm/s) of a piston is v = 6t - 6t^2, where t is the time (in sec). Find the displacement s of the piston after 0.75 sec if the initial displacement is zero.
What are the design implications for the location and positioning of solar cells? Explain why the use of solar cells might be more appropriate in some regions of the country.
What is the magnitude of the frequency component at 30 kHz? The square wave is passed through an ideal rectangular low pass filter that completely attenuates all frequencies higher than 35 kHz. Write down an equation for the spectrum at the output ..
Finding rms current through Capacitor and Inductor, A circuit consists of a sine wave signal generator and a reactive component (L or C). The output of the generator is a sine wave with a peak amplitude of 8.8 volts at a frequency of 10.0 kHz.
