Three capacitors, of 6 μF, 8 μF and 10 μF respectively are connected in parallel across a 60 V supply. Calculate
(a) the total capacitance,
(b) the charge stored in the 8 μF capacitor and
(c) the total charge taken from the supply.
The preamplifier is fed by an antenna with noise temperature of 300 K (this is the temperature of Earth viewed from space). Find the temperature of the overall system using a preamplifier gain of 15 dB and also for the preamplifier gain found in p..
Imagine a circuit consisted of two DC power sources of 12 volt and 10 volts. The negative terminals of these power sources are wired together. Assume that the positive terminals of these power sources are labeled as A and B respectively.
Explain the difference between TDM and TDMA.
he sensor to be used has a transfer function of ? Q volts, where Q is in gal/min, and an output impedance of 2.0 k?. Tests show that the output of the sensor has 60 Hz noise of 0.8 V rms. Design a signal-conditioning system, including noise filter..
DESCRIBE THE DIFFERENCE between instructions:
A capacitive sensor consists of two plates in air. The plates are 50 mm square and are separated by a distance of 1.2 mm. A sheet of a dielectric material of 50 mm square and 1 mm thick can slide between the plates.
A serial input finite state machine has one input and one output. The output becomes 1 and remains 1 thereafter when at least two 0's and at least two 1's have occurred as inputs, regardless of the order of occurrence. Draw a state diagram for the..
A lottery winner got $350,000 that invested as follows: part of it in a money market account, part in municipal bonds, and part in a mutual fund. After one year, he recieved a total of $24,200 in simple intersest from the three investments.
Design a 25 W Class B public address amplifier with one input that will operate off of a pair of batteries of equal voltages and provide a voltage gain of 100. Assume that available op amps have againbandwidth product of 1 MHz and can come within ..
A propagating electromagnetic wave is described as follows (inset your own equation for Electric field). Determine if the wave is linearly polarized, left-hand elliptic polarized, right-hand elliptic polarized, left-hand circular polarized, or rig..
The current in the bias resistors should be no more than 10 percent of the drain current- Determine VGS, ID, and VDs. Sketch the load line and plot the Q- point.
Assume a binary PCM system in which the system ratio of the bit energy to the one-sided noise density at the receiver input is 10 dB. Assume that the probability of error for any value of the independent variable off the scale can be approximated ..
