Design a class - A transformer-coupled emitter-follower amplifier to deliver 10 W to an 8 Ohm speaker. The ambient temp is 25 C and the maximum junction temp is Tj max = 150 C. assume the thermal resistance value are dev-case = 3.2 C/W, case-snk = .8 C/W, and snk-amb = 4 C/W. specifiy the power supply voltage , transformer turns ratio, bias resistor values , transistor current, voltage and power rating.
Charges +Q and +3Q are seperated by a distance 2m. A third charge is located such that the electrostatic system is in equilibrium. Find the location and the value of the third charger in terms of Q.
The ATSC broadcast television system used in the US transmits video signals at an average rate of 18.34 Mbps and employs 8-VSB modulation.
What is the shape of the spectrum of the signal? What is the extent of the spectrum in the frequency domain? What is the unit that is applied to the magnitude of the spectrum?
By that I mean, how does IM/IT help KL carry out day-to-day operations and transacting, how does it aid management processes, and does it enable KL product and service innovation?
Calculate the S/N ratio for a receiver output of 4 V signal and 0.48 V noise both as a ratio and in decibel form. (69.44, 18.42dB)
How tall must the antennas be if the link operates on a frequency of 2.450Ghz, D1=5miles, D2=11miles, and the obstruction is 60 feet high?
An LED with a rated range of VF = 1.4 V to 1.8 V at IF = 20 mA is connected to a driver circuit with a peak output of 14V. What value of current-limiting resistor would be needed to limit the LED current to a maximum value of 20 mA
The global radiation at the solar noon on a summer solstice in Albuquerque, New Mexico (latitude 35° N) is 60mw/cm^2. Assume that (a) 30 % of this irradiance is diffuse radiation and (b) the ground surrounding a PV module is non-reflecting
