For the configuration of given figure:
a. Convert the current source and 6.8-Ω resistor to a voltage source.
b. Find the magnitude and direction of the current I1.
c. Find the voltage Vab and the polarity of points a and b.
The battery is made by connecting 5 unit cells in series and then by connecting 7 of these series cells in parallel. Each unit cell has the voltage of 1.25 V and the internal resistance if 3.4 Ohm.
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.
The open-loop response of an uncompensated op-amp. Compensation is to be applied to the amplifier to make it unconditionally stable. Estimate the frequency at which the breakpoint of the compensated response must occur.
Consider the Bode magnitude plot for the transfer function of a certain filter given by H(f) = Vout/Vin = 50(j(f/200)/1+ j(f/200))- What is the slope of the low-frequency asymptote? What is the slope of the high-frequency asymptote?
design an amplifier to sense the opencircuit output voltage of a transducer and to provide aproportional current through a load resistor. the equivelent sourceresistance of the transducer is specified to vary in the range of 1k to 10 k.
digital radio link has a bandwidth of 8 kHz and support a transmission of 87 kbps. According to Nyquist how many bits per symbol are required to modulate the signal Remember to use an integer number of bits.
A walker's cassette tape player uses four AA batteries in series to provide 6 V to the player circuit. The four alkaline battery cells store a total of 200 watt-seconds of energy. If the cassette player is drawing a constant 10 mA from the battery..
Design a datapath which inputs three 3-bit unsigned numbers x,y, and z. If z is the binary representation for 3 or 7, output x + y. If z is the binary representation of 4 or 6, output x + z. If z is anything else, output y + z.
