(a) The speech quality for a particular mobile communication system is just acceptable when the received power at the terminals of the mobile receiver is -104 dBm. Find the maximum acceptable propagation loss for the system, given that the transmit power at the base station is 30W, base station feeder losses are 15 dB, the base station antenna gain is 6 dBi, the mobile antenna gain is 0 dBi and the mobile feeder losses are 2 dB. Express the field strength at the receiver antenna in dBμVm-1
(b) Calculate the maximum range of the system described in (a) using: A. the free space loss B. the plane earth loss, assuming a frequency of 2 GHz and antenna heights of 15 m and 1.5m

A 60 Hz, 765 kV three-phase overhead transmission line has four ACSR 1113 kcmil 54/3 conductors per phase. Determine the 60 Hz resistance of this line in ohms per km per phase at 50o C.
A certain type of power resistor comes in the following rating:3w,5w,8w,12w,20w. your particular application requires a resistor that can handle approximately 8w.
Each time you apply a theorem or law of boolean algrebra, mark your paper clearly to indicate which terms were used to add or delete other terms, or indicate which terms were combined. Simplify algebraically
Identify the steps involved in the delivery of a letter from the sender to the addressee. How are these steps similar to OSI layers' functions such as addressing, routing, resource sharing, error checking, and connectionless vs. connection-oriente..
Implement a magnitude comparator circuit which compares two-bit binary numbers A and B, and provides 3 outputs (A>B, A=B, A
A three phase generator is producing power for a balanced load. Each phase provides an rms voltage of 690 V and an rms current of 1000 A. The angle between the voltage and current in each phase is 20 degrees.
A 150 MHz uniform plane wave in normally incident from air onto a material whose intrinsic impedance is unknown. Measurements yield a standing wave ratio of 3 and the appearance of an electric field maximum at 0.3 wavelengths
Design finite state machine that starts with even number of 1s and followed by odd numbers of 0s. Design finite state machine that starts with odd number of 1s and followed by even numbers of 0s.
what is the conversion efficiency of an amplifier in which the effective value of the current through a 2.2k ohms load is 5 mA and the drain on the 18-V dc supply is 3.8mA. What will happen to the output AC signal if the DC level is insufficient
From a high-level perspective, what is the major difference between the LM324 and the LF347. Which of the performance characteristics are significantly different because of this.
The counter should increment on the rising edge of an input signal we'll call COUNT. Another input called CLEAR should have the effect of setting the counter to zero if CLEAR = 1 when COUNT is asserted.
