Refer to the network of Figure 6-62:
a. Calculate the values of R1, R2, R3, and R4 so that the total resistance of the network is 100 kΩ.
b. If R4 has a current of 2 mA, determine the current through each of the other resistors.
c. How much current must be applied to the entire network?
Design a combinational circuit that multiplies two 2-bit numbers, a1,a0 and b1,b0, to produced a 4-bit productc3,c2,c1,c0,. Use AND gates and half-adders.
Do either or both of the reasons you gave in part (a) above also apply to a point to point voice link using frequency modulation? c. Which parameter of an FM transmission determines whether it is wideband or narrow band?
A tank of fluid employed in a chemical process is being monitoredwith three sensors. The sensors measure temperature, pressure andfluid level. If all the sensor measurements are in the normalrange, the sensor outputs are low.
The 3phSM is used in a pumped storage application which has a head of 250 m. When pumping or generating, it operates at 84% efficiency, rated stator conditions. Determine the turbine flow when (1) generating and (2) pumping.
Suppose that the cost of electrical energy is $0.12 per kilowatt hour and that your electric bill for 30 days is $60 (power usage only, not including other charges or taxes) Assume that the power delivered is constant over the entire 30 days.
Design a decade counter (negative edge-triggered counter) using flip flop circuit that can be used to perform binary counting. Show the timing diagram for the input and four outputs of the decade counter.
A 25 cm length of coaxial cable with inner radius of a=2 mm, and the outer radius of 4 mm, is filled with air. If the total charge on inner conductor is 50nano-Coulombs, what are the charge densities of the inner and outer conductors
Show the floating-point version of the digital filter.
A pulse is used to measure the frequency response of a system. Since we expect the frequency response to extend to 20 kHz, select a pulse whose magnitude spectrum is constant within 1% out to 20 kHz.
Assuming that only integer multiples of a unit bipolar transistor having IS = 3 x 10-16A can be placed in parallel, and only a single voltage source, VB, is available (Fig. 4.54), construct the required circuit with minimum number of unit transist..
The voltage response for the circuit is known to be v(t)= D1te^-500t + D2e^-500t. The initial current in the inductor is -10mA and the initial voltage on the capacitor = 8V. The inductor has an inductance of 4H,
Computer the following assuming each number is a two's complement number and indicate the inputs and final result in decimal. Also, indicate if the number overflows. a. 01 + 1011 b. 11 + 01010111 c. 1101 + 110 d. 01 + 10 e. 111 + 111111
