A digital oscillator delivers two sinusoidal signals at 10 kHz and 12 kHz, sampled at 60 kSa/s. What is the minimum FFT length N that will result in a leakage-free FFT if both tones are present?
a radio antenna operating at 1.5 MHz has an input impedance of 6+j226 ohms. A capacitor is connected in series with it for tunning purposes. compute the valur of capacitance needed to tune the antenna to resonance.
given a triangular plane in the coordinate plane slanted with a surface bounded by the closed path. how to find the magnetic flux in that plane
Write a 68000 assembly language subroutine, ROTMEM, which rotates the elements (words-size) of an array stored at location point to by (A0). The depth of the array is stored as the first element.
You deposit 10% of your annual salary at the each of each year in a retirement account. F= Future worth A1= first annual deposit n=number of years g=geometric gradient F=A1(1-(1+g)^n(1+i)^-n/(i-g))(1+i)^n use Matlab to graph the function.
Write a ladder logic program needed to implement each of the following (assume inputs A, B and C are all normally open toggle switches).
(1) What is a Darlington transistor configuration (2) What are its advantages and disadvantages (3) When is a Darlington configuration used (4) Can Drlington transistors be purchased (5) Do they come in complimentary pairs
Consider the following differential equation, where x(t) is the input and y(t) is the output: d/dt y(t)+5y(t)=2x(t) Suppose the input is x(t) = 4u(t) and the initial condition is y(0-) = 6 1. What is the impulse response for the system
find the complete functions, p(t) and w(t) supplied by the element, not just a number, and graph p(t) and w(t). Choose appropriate intervals of time for your graphs. Assume that both v(t) and i(t) are zero for t
In the differential amplifier shown in the schematic, R1 = R2 = 10 k ohm; R3 = R4 = 100 k ohm. Assume the ECG voltage at V1 = 100 mV, and the ECG voltage at V2 = - 100 mV. There is a power line interference of 200 mV at both input sites.
Design a 4-bit decrementer using Half-adders and inverters as building blocks. The circuits impleents A-1=S. Draw the circuit diagram. Hint: consider addtion of the 2s complement of -1 =1111. Begin with a 4-bit adder circuit constructed with 1-bit..
sketch the spectrum
What is the symbol rate and what is the bandwidth occupied by the 16-QAM signal? The link must maintain a BER no higher than 10^-6. What is the minimum CNR in the receiver to meet this requirement?
