A digital TV station transmits on Channel 7 with an ERP of 18 kW. The signal from this TV station is received 50 miles away via a LOS path with a receiving antenna that has a gain of 8 dB on Channel 7. Calculate the power at the receiving antenna output-connector in:
(a) dBm units.
(b) in dBmV units across a 75 ? load.
(c) in μV across a 75 ? load.
Use a frequency of 1 kHz to determine the inductive and capacitive levels required for the input files. In each case write the required input file.
A discrete-time LTI system has the impulse response h[n]. Use linearity and time invariance to determine the system output y[n] if the input is h[n]={-2:n=-1, 3:n=0, 2:n=3, -4:n=5}
npn transistor has a CBJ with area 150 times that of EBJ. If Is= 5 x 10^-15 find the voltage drop across EBJ and CBJ when each is forward biased and conducting a current of 1mA. Also find the forward current each junction would conduct when forwar..
Compute the energy consumed by the load in 24 h period.
The numbers N, A, and B are usually published so that everyone knows them. Suppose A= 21, B= 5, N= 8, and the initial value (or seed) is X(0)=1. Write down the first six decimal numbers that are generated by this algorithm.

Design the basic cell of a universal shift register to the following specifications. The internal storage elements will bepositive edge-triggered D flip-flops. Besides the clock, theshifter stage has two external control inputs, S0 andS1, and thre..
An input signal of 10V at 0 degrees is applied to a series RLC circuit with resistore R=100 ohm, inductor L=40 mH, and capacitor C = 0.5uF. determine what is The value of the total circuit complex impedence.
A portable battery supplies electricity to an external circuit for 2 hours. The voltage across the terminals of the battery is observed to increase from initial voltage of 5V to 10V (linearly) and the current increases from 1A to 2A (linearly) in ..
Over a period of 10 seconds, how much charge moves through the element. If electrons carry the charge, which terminal do they enter. How much energy os transferred. Is it delevired to the element or taken from it.
resistor: a volt-ohmmeter with an internal impedance of 1000 Ω/V and an EVM with an impedance of 11 MΩ. Calculate the voltage indicated by each of these devices.
a square wave of 1000Hz is introduced into an ideal band passfilter (bandwidth = 100Hz) that is tuned to 5000Hz. The signal output has an amplitude of 0.1V. The filster is thenreturned to 9000Hz.
