1) An Op-Amp is powered with a single 12V supply. If Vin(-) = 5V and Vin(+) = 3V, what is the output voltage if there is no feedbackresistor, Rfb?
2) An Op-Amp is connected in the inverting configuration with Rin = 4k? and Rfb = 1k?. If the input voltage is 4 VDC, what is Vout?
3) If the input voltage to a Full-Wave Bridge Peak Rectifier is vi(t) = 10.4sin(600t) Volts, what is the peak output voltage. Assume alldiodes have a 0.7V drop, (ie. VD = 0.7V).
4) For the previous problem, if the resistor in the circuit is equal to 10k? and the capacitor is equal to 1µF, what is the DC (or average) voltage across the resistor?
"Power Outage" refers to that the receive signal power falls below a certain threshold. Consider for a RF signal in a Rayleigh fading channel with average receive signal power 22 = - 80dBm. What will be the power outage probability of this channel..
