A one meter of annealed copper 2.5 cm in diameter is drawn until its resistance is 100 times the initial resistance, its diameter afterward is?
List the sequence of microoperations for fetching a memory reference instruction and then placing the operand in DR. Start from timing signal T0.
Draw a block diagram of the computer showing the memory and registers. (Do not use a common bus).
A computer uses a memory of 65,536 words with eight bits in each word. It has the following registers: PC, AR, TR (16 bits each), and AC, DR, IR (eight bits each). A memoryreference instruction consists of three words: an 8-bit operation- code (one word) and a 16-bit address (in the next two words). All operands are eight bits. There is no indirect bit
A current of 90 A is shared by three resistances in parallel. The wires are of the
same material and have their lengths in the ratio 2: 3: 4 and their cross-sectional areas
in the ratio 1: 2: 3. Determine current in each resistance
Draw the logic diagram of all the cells of one word in an associative memory. Include the standard read and write logic and the match logic.
1) Find the spectral components of a periodic train of a square pulse with an even symmetry by applying Fourier series analysis. Consider the period of 1 s for the repetition of the square pulse.
(3) Why do you observe ripples in the synthesis of the periodic train of square pulse?
(4) Why are the ripple absent in the synthesis of the periodic train of triangle pulse?
(5) How the number of ripples is related to the number of harmonics in the
synthesis of the periodic train of square pulse?
(6) What is the effect of varying the number of samples and the frequency as in the steps (7) and (8), respectively?
How does the sine and cosine functions affects the symmetry (either
even or odd) of the synthesised periodic signals?
A non-inverting amplifier is working on 120 mV with input resistance of 300 and feedback resistance of 1500. Calculate its gain and design the circuit by showing all parameters.
