Given the narrow audio bandwidth of a telephone transmission facility, a nominal SNR of 56dB (400,000), and a distortion level <0.2% is required. a) What is the theoretical maximum channel capacity (Kbps) of a traditional telephone line? b) What is the actual channel capacity?
a) What are the key observations of nerve growth in an electric field and what are the conditions (field strength, duration, treatment protocols) for electric fields that promote nerve growth
Design a 3-stage MOSFET amplifier that provides a differential gain |vo/vd| > 20V/V, a small common-mode gain, and an output resistance Ro >1kΩ. The amplifier is to drive a load RL = 10kΩ. The frequency of the signal source is 10 kHz.
Given coaxial cable with an inner conductor with radius a and anouter conducrot with radius b, find B forρ>b when the inner and outer currents are +100[mA] and-90[mA], respectively, and both conductors are centered along thez-axis.
consider the following two first-order transfer functions H1 (z) = z + b/z + a , a = 0.3, b = - 0.4 H2(z) = bz + 1/z + a , a = 0.3, b = - 0.4 (a) draw the pole-zero plot for both transfer function H1(z) and H2(z)
A voltage regulator circuit uses a Zener diode that exhibits a total voltage of 6.8 V at 5 mA. The resistance Rz = 20 O. The supply voltage V+ is nominally 10 V but can vary by ±1.5 V, and the resistance R = 0.5 kO (use the regulator circuit diagr..
A plane electromagnetic wave of frequency 300 MHz propagates in homogeneous sea water (ε=80,σ=1) along the z-axis. The effective field strength at the excitation point(point of origin) is 0.1V/m.
Write an algorithm in pseudo code that finds all prime numbers between 2 and 100. You may use any algorithm to compute them, but be sure that your pseudo code meets the three requirements of an algorithm: definiteness, effectively computable, and ..
Design a DC power supply that provides -95v +/- 5v to a 2 amp load (energy absorber). The input source is a 100 volt peak sinusoid, 60 Hz. You may use any basic circuit element. State the values of all circuit elements (in ohms, farads, etc).
A boost converter is to be employed as part of a power factor correction circuit. The input is 220 v rms 60 Hz single phase and the output is 400 V dc. It is to supply a dc load drawing 10 A.
Consider an electric circuit consisting of a parallel RC circuit,where the resistance R is one kilo-ohm and the capacitance is 100 microfarads. A current source Is(t) is applied in parallel to the resistor and the capacitor.
designing a digital thermometer, which will display temperatures from -60 degrees F tp +140 degrees F. (thesystem displays the temperature to the nearest degree, so you will not need to display fractions of a degree.
Complete the following table of flip-flop excitation values required to produce the indicated flip-flop state changes, where y indicates the present state and Y the desired next state of the flip-flop.
