Design a band pass filter using capacitive-gap coupled resonators. The response should be maximally flat, with a center frequency of 4 GHz, a bandwidth of 12%, and at least 12 dB attenuation at 3.6 GHz. The characteristic impedance is 50 . Find the electrical line lengths and the coupling capacitor values. Use CAD to plot the insertion loss versus frequency.
Consider a dipole where there is a charge of -6 uC at the point (2X10^-10 m,0) and a charge of +6 uC at the point (+2X10^-10 m,0).

An 8x1 multiplexer has inputs A, B, and C connected to the selection inputs S2, S1, and S0, respectively. The data inputs I0 through I7, are as follows: I1 = I2 = I7 = 0; I3 = I5 = 1; I0 = I4 = D; and I6 = D'. Determine the Boolean function that t..
Two batteries with emf's of 1.5V and 1.2V and internal resistances of 0.50-ohm and 0.80-ohm, respectively, are connected in parallel with + terminals together. a.) Determine the current they would deliver to an external resistance
An amplifier operating from a single 15-V supply provides a 12-V peak to peak sine wave signal to a 1-k ohm load and draws negligible input current from the signal source. The dc current drawn from the 15-V supply is 8mA.
A half-wave rectifier circuit with a 1-k ohm load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer. It uses a silicon diode that can be modeled to have a 0.7-V drop for any current.
