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?
A causal linear time-invariant continuous-time system has impulse respose h(t)=(sin t)u(t-2). Compute the output respone y(t) for all t is greater than 0. compute the output response y(t) when x(t)=u(t) -u(t-1).
Whatever degree is the announcement "The threat of the Cuban Miissile Crisis has been not kidding misrepresented" genuine?
Once the sequence starts it will complete.If E=1 during the last output in the sequence the sequence repeats. Otherwise if E=0 the output remains constant at 1. The first thing they want in this problem is a Moore state diagram for the circuit.
The output is 1 when the pattern abca has occurred an even number of times in x(0,t). Give a state description of the system. Use a state vector approach and a minimum-number-of-states approach.
A receiver with a synchronous detector receives a barely intelligible message since the (s/n)d =4 db . it has been determined that the transmitter has ST= 100 W , μ = 0.9 and SX=0.5. What is the minimum value of ST if envelope detection were used.

A constant (dc) current i(t) = 3 mA flows into a 51-F capacitor. The voltage at t = 0 is v(0) = -21V . The references for v(t) and i(t) have the passive configuration. A) Find the power at t=0. B) State whetehr the power flow in into or out of the ..
Problem (1): For the circuit shown in Figure PI: a) Using the Node-Voltage method. find the three nodes voltages VI. V2 and V3 b) Calculate the power delivered or absorbed by each source.
In the circuit in Fig. 11.25, the 60-Ω resistor absorbs an average power of 240 W. Find V and the complex power of each branch of the circuit. What is the overall complex power of the circuit?
A load consisting of a 480 ohm resistor in parallel with a (5/9) uF capacitor is connected across the terminals of a sinusoidal voltage source, vg, where vg=240cos5000t V. a) What is the peak value of the instantaneous power delivered by the source
A step down chopper is to be used to supply power from 600 overhead wire to commutator motor on a trolley bus . The motor may be modeled as a generated direct voltage in series with a resistance of .2? and inductance of 25mH.
