An FM receiver has an input tuner bandwidth of 150KHz. The pre- Limiter circuitry has a Noise Figure of 8dB and an input Noise Temperature of 1800C. Given an FM demodulation noise improvement of 17dB, determine the minimum receive signal power to achieve a post detection signal to noise ratio of 35dB.
A 300-km bundled 500-kV, 60-Hz, three-phase completely transposed overhead line has three ACSR 1351-kcmil conductors per bundle, with the bundle spacing 0.5 m. The horizontal phase spacings between bundle centers are 10, 10, and 20 m.
Design a 2-bit counter that, when v = 1, counts in the repeating sequence: 0, 3, 1, 2, and when v = 0, counts in the reverse direction. (a) Construct a state diagram and state table. (b) Implement the counter using D flip-flops.
Suppose a pure Si crystal has 5 × 1028 atoms m-3. It is doped by 1 ppm concentration of pentavalent As. Calculate the number of electrons and holes. Given that ni =1.5 × 1016 m-3.?
An analog signal has a bandwidth of 37 kHz and must be digitized in an ADC. The peak voltage is 7V and you need to maintain a resolution of 0.078V. Find the number of bits per sample and then
a lowpass butterworth filter has a corner frequency of 1 khz and a roll-off of 24 db per octave in the stopband. If the output amplitude of a 3 khz sine wave is .1 V, what will be the output amplitude of a 20 khz sine wave if the input amplitudes ..
a) Assume B1 = ax2 - ay10(mT), find B2 and the angle that B2 makes with the interface. b) Assume B2 = ax10 +ay2(mT), find B1 and the angle that B1 makes with the normal to the interface.
The 741 op amp is usually modeled on specification sheets as a voltage amplifier having the following parameters: Rin = 1 M, Av = 100,000, and Rout = 100 Using this information, develop equivalent circuits for the 741 as a current amplifier
Suppose you are to construct a logic circuit with inputs {A,B,C} and output {F} The logic is such that "F" is asserted only when "A" or "B" are asserted and "C" is not. First draw and complete the truth table
In the presentation, the presenter, Mr. Rob Tucker discussed three types of disturbance mitigation responses or measures. List the three mitigation types and give a short definition of each of the mitigation type.
Which transistor bias circuit arrangement provides good Q-point stability, but requires both positive and negative supply voltages.
The speed of data communication link is 16Kbits p/s. The voltageof each sample vary from 0 to 2V. The length between the digitized levels is 0.125 V. Find the number of samples that can be sent in 1 minute
If we use the PC-relative addressing mode, and want to allow control transfer between instructions up to 50 locations away, how many bits of a branch instruction are needed to specify the PC-relative offset
