A sinusoidal signal is riding on a 2 v DC offset (in other words, the average value of the total signal is 2 v). Design a circuit to remove the DC offset and amplify the sinusoidal signal (without phase reversal) by a factor of 100.
Each of the capacitance units is built of 4 similar 100V capacitors. Determine the capacitance of each capacitor.
implement the function. Count the number of NMOS and PMOS transistors and the number of inverters. The available inputs are A, B, C, D and E (no inversions). X = AB + A(B + C) Y = A + B + C Z = A + BC
Calculate the Fourier Transform of f(t) = 5 sinc(-2t/100), and graph the magnitude and phase as a function of f. If the signal of problem 1 is delayed by 0.1 ms. What is the new Fourier Transform.
If the semiconductor depicted in the graph below is germanium at room temperature, what is the value of n (the density of electrons in the conduction band) at x=L
A signal contains a mixture 30 , 100 and 240 Hz Sine waves and also contains wideband noise whose spectrum is from 500 Hz up to a 1000 Hz. Describe a filtering technique that can be used to cleanly separate 30, 100 and 240 Hz from each other and a..
A glass tube with a cross-sectional area of 9^-2 m^2 contains an ionizd gas. The densities are 10^15 positive ions/m^ and 10^11 free electrons/m^3. Under the influence of an applied voltage, the postive ions are moving.
A four-input summing amplifier has all input resistors at 10 k and the feedback resistor equal to 2.2 k. If the input voltages are all equal to 2 V, what is the output voltage
Calculate the distance, D at which communication from the space craft will be lost again? Assume both antennas are ideal.
Design and sketch a band pass filter consisting of an RC high-pass filter with a cutoff frequency of 300 Hz and an RC low-pass filter with a cutoff frequency of 700 Hz. Carefully select the R and C of each filter so that one filter does not load t..
a) It is required that the propagation delay be limited to 60 psec. Find the required device widths b) Find the High and Low noise margins, i.e. NMH and NML. c) What is the peak current drawn from VDD during switching of the inverter What is the aver..
A aperiodic signal x(t) = 2sinc(2t) is multiplied by a periodic rectangular pulse train s(t) with fundamental frequency F0 = 4 Hz and the fundamental rectangular pulse given by p(t) = 1, -1/80
