Design three versions of the combinational circuit whose input is a4-bit number whose output is the 2's complement of the inputnumber, for each of the following cases:
a) The circuit is a simplified two-level circuit, plus inverters asneeded for the input variables.
b) The circuit is made up of four identical two-input, two outputcells, one for each bit. The cells are connected in cascade, withlines similar to a carry between them. The value applied to therightmost carry bit is 0.
c) The circuit is redesigned with carry lookahead-like logic inorder to speed up the circuit in part (b) for use in largercircuits with 4n input bits.
A causal linear time-invariant continuous-time system has impulse respose h(t)=(sin t)u(t-2). Compute the output respone y(t) for all t is greater than 0. compute the output response y(t) when x(t)=u(t) -u(t-1).
A radar transmits a monotone pulse of 5-s duration. Suppose the radar were redesigned so that the same pulse envelope is frequency modulated with linear FM over 100 MHz. (a) What is the possible new range resolution
Given the following: i) The column vectors: X1=[2 4 6]'; X2=[4 5 7]'; X3=[7 8 3]' % Note the above are column vectors (% In Matlab, ' means Transpose). ii) The matrix: A=[X1 X2 X3]. 1)B=A'; % In Matlab, ' means Transpose. This defines B.
A Motorola 68000 microprocessor-based data acquisition system incorporates memory ( EPROMS and SRAMS), an Analog-to-Digital Converter (A/D), a Centronics Parallel Printer, and a very simple I/I Device made up of a single push-button switch.
b) What are the equilibrium electron and hole concentrations at 300K and 500K (hint: You will have to find Nc and Nv at 500K, but it isnt necessary for 300K) c) Why does the mobile carrier concentration increase at high temperatures
determine the capacitance of a parallel-plate capacitor having plates 14cm by 30cm separated by 0.01mm. The dielectric has (epsilon)(r)=15
A lossy transmission line at 1GHz has the following characteristics: Z0= 50.0 ohms alpha= 0.01 dB/m, Betta=8 rad/m. Determine R, L, G and C for the line
A silicon wafer has a uniform doping density of 4x10^19 atoms cm^-3 of Arsenic and 4x10^19 atoms cm^-3 of Phosphorus. Assume that all atoms are fully ionized at room temperature.
Transfer function : key informaiton, A linear time-invariant discrete-time system is excited by the input x[n] = d[n] + 2u[n-1] (d represents δ(delta)). The resulting output response with zero initial conditions is y[n] = ((0.5)^n * u[n]). De..
A CG amplifier when fed with a signal source having Rsig = 200 ohms is found to have an overall voltage gain of 10V/V. When a 200 ohm resistance is added in series with the signal generator the overall voltage gain decreased to 8V/V.
g0 is the acceleration of gravity at the surface of the Earth, A is the altitude, and Re is the radius of the Earth, approximately 6,380 kilometers. What is the value of g at an altitude of 20 miles in unites of meters per second squared
Design a Mealy circuit has two inputs, X and Y, and two outputs, Z and W. If the two inputs are 0 at the previous clock rising-edge and then 1 at the next clock rising-edge, then an output Z = 1 (else Z = 0). If one of the inputs is set to 1 and t..
