Explain why the low value (0) for the 'output' of a digital logic gate is lower than the low value for the 'input' of a digital logic gate? (This is the case for CMOS and Bipolar logic). Look at a specsheet.Are the high values for input and output different also. If so whyand if not why not?
Describe how you would design a Gray code counter without VHDL?
Consider the analogue cosine signal y(t) = COS(8.8pit). It is sampled using a sampling interval of T = 0.5 sec. What is meant by the term aliasing in regard to signal sampling What is the minimum sample rate that should be used to avoid aliasing
A certain antenna has a radiation resistance of 51 ?, and an ohmic (loss) resistance of 10 ?. If a current of 2 A is driving the antenna, calculate the following: a) the power radiated. b) the power lost due to heat.
Find out the birthday (month and day but not year) of a randomly chosen person. What is the sample space of the experiment. How many outcomes are in the event that the person is born in July
The data inputs I0 through I7 are wired as follows: I0 = I1 = 0, I2 = I6 = , I3 = I5 = I7 = 1; and I4 = D. (a) Determine the Boolean function that the MUX implements. (b) Implement the function using a 4×1 MUX with minimum extra logic gates.
A 1GB DRAM uses 4-bit data and has equal-length row and column addresses. How many address pins does the DRAM have?
A 25 cm length of coaxial cable with inner radius of a=2 mm, and the outer radius of 4 mm, is filled with air. If the total charge on inner conductor is 50nano-Coulombs, what are the charge densities of the inner and outer conductors
An amplifier using balanced power supplies is known to saturate for signals extending within 1.2 V of either supply. For linear operation its gain is 500 V/V. What is the rms value of the largest undistorted sine-wave output available,
Three-phase transformers are grouped according to the phase shift between their primary and secondary phase voltages. Discuss the transformer classification adopted by the standards and elucidate the terminology used for describing various transfo..
