A 64k x 16 memory uses coincident decoding by splitting theinternal decoder into X-selection and Y-selection.(a) What is the size of each decoder, and how many AND gates arerequired for decoding the address?(b) Determine the X and Y selection lines that are enabled whenthe input address is the binary equivalent of(A5BC)16(c) If two-dimensional address multiplexing is also used, howmany address pins are needed?
A Newton's ring apparatus is to be used to determine the radius of curvature of a lens (see the figure below and Problem 75). The radii of the nth and (n+16)th bright rings are measured and found to be 0.129 and 0.317 cm
The signal x(t) = 2 - sin(4.5t - pi / 4) + 3 cos (24t + pi / 2) is input into a system with frequency response H(omega). Find the output signal y(t) if: H(omega) = rect(omega/80) H(omega) = 2 - 2rect(omega/8) H(omega) = sin c(omega/20)
A synchronous binary counter is used to divide a 1 MHz input frequency to 3.90625 kHz. What is the MOD number of the counter and how many flip-flops are required
if 4 cells each rated for 2v, 0.15A connected as batterries in three different ways. find voltage and current rating of each type. (Hint - all in parallel, all in series, two groups of series connected in parallel)
Systems that operate under real time conditions need to be causal - that is, they can only process present and past inputs. When no real time processing is needed the system can be non-causal.
If the speed of the crate at A is 15 ft/s which is increasing at a rate v=3 ft/s^2, determine the magnitude of the acceleration of the crate at this instant. [crate is on an incline sliding back toward the orgin at a distance of 10ft
b) Calculate the armature current at start c) The motor is now used as a generator. Calculate the speed of the machine if the armature current is 80A and there is a 230V at the motor's terminals. Assume a constant flux.
A lossless transmission line is embedded in a medium having a dielectric constant of 9. The per-unit length capacitance of the line is given as 100 pF/m. a.Find the wave velocity in the medium.
determine the voltage drop across the 20 Ohm resistor with respect to the 48 V source. I'm having difficulty understanding why the voltage comes out to a negative 12 V, then to a negative 8 V.
average velocity of v meters/second. If the concentration of free electrons is 10^{29} electrons per cubic meter and if they are uniformly dispersed throughout the wire, then what is the average velocity of an electron
Given the following voltage and current expressions, show the expression for the voltage across R2 in the circuit Note, R1=100 ohm, R2=300 ohm, and R3=200 ohm: a) v(t) = 10 cos (377t + pi/4) V b) i(t) = 5 cos (754t - pi/3) mA
Design a 4-bit synchronous up/down counter using T flip-flops. The circuit has one input up' /down such that input 0 means count up and input 1 means count down. up' is "up" with a bar over it
