a) Present the following expression in both standard forms, namely, sum-of-products (SOP) and product-of-sums (POS), using properties of Boolean algebra: consider deMorgan's and distribution laws.
b) Draw the gate-level circuit diagrams for three variants using generic logic gates in the ISE library and verify the functional behavior of function A with ISim for various input signals inaccordance with the system description (no propagation delays will be observed). The variants to include: direct implementation of equation (1) with AND, OR and NOT gates, two-level implementations (2) NAND-NAND and (3) NOR-NOR based on the SOP and POS forms, respectively. Identify the critical path for variant (1) only. Select the combination of static (high, low levels) and dynamic (square-wave) signals to measure the propagation delay.
c) Estimate the propagation delays of implementations (1), (2) and (3) using typical propagation delay data in the timing specifications of the logical gates of CD4000 family. Take the average propagation delay for 1-0 and 0-1 output transitions.
Expression : A (W, D, E, X, S) = (W'+D')?E?X' + S
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
Let the probability of a bit error be p, and the length of a data frame be N. Find the probability of 1, 2, 3, and 4 bit errors occurring in the frame. a) Tabulate the results for N = 1000, 10000, and 100000 bits, for p = 10-6, 10-8, and 10-14
1. Determine the minimum value of gain K when Gc(s)=K, so that the steady-state effect of a unit step disturbance Td(s)=1/s is less than or equal to 5% of the unit step (y(inf)=0.05). 2. Determine whether the system using the gain of part 1 is stab..
We have an amplifier with a 1 MHz bandwidth and a 20 mV input signal. The input noise = 1 mV, output signal 6.0 mV, and output noise = 1 mV. Find: (a) SNR at the input (b) ..
A certain engine lathe can be purchased for $330,000 and depreciated over three years to a zero salvage value with the SL method. This machine will produce metal parts that will generate revenues of $220,000 (time zero dollars) per year.
An Aluminum wire with a square cross section 2mm on a side is carrying a current of 1.5amps. Aluminum has a resistivity of 2.69*10^-6 ohm-cm and an atomic volume of 10cc/mol. Assuming aluminum has three free electrons per atom
