A coaxial cable has an inner conductor of radiua a = 0.8 mm and an outer conductor of radius b = 2.6 mm. The conductors have σc=5.8x10^7 [S/m] uc=uo. ε=ε0 they are separated by a dielecric material having σ = 10^-5[S/m], u = uo, ε=3.5ε0.At 80 MHz, find L, C, G and R.
Design a mod-6 UP/DOWN counter: A) Using JK flip-flops and the state equation method. (Show the state diagram, state table, state equations, flip-flop input equations, and the logic diagram.)
A telephone switching board can handle 120 phones. Assuming the following, and determine the outgoing traffic intensity and the number of channels
A standard silicon NPN BJT is to be used as an amplifier. The emitter voltage is biased at 4 volts, the base is biased at 5 volts, and the collector is biased at 10 volts. Will this circuit perform as desired? Why or why not.
Three capacitors are found that each have an impedance of -j2.0, and they are connected in parallel with the load in a wye configuration. Determine the power factor of the combined load as seen by the source.
What is the current if the voltage source is reduced to 80% of the original value. Will the current increase or decrease and by how many percent if the total resistance of the circuit is 10% of its original value.
