Problems 1. A two-stage power amplifier with a 50 dB gain and loss of -10 dB has an output power of 100 W. What is the input power? 2. An AM broadcasting station is transmitting a frequency of 950 kHz with a total bandwidth of 10 kHz. (a) What are the cutoff frequency? (b) What is the modulating frequencies? 3. The upper and lower cutoff frequencies of a resonant circuit are found to be 8.05 and 7.95 MHz. What is the quality factor Q? 4. What is the bandwidth of a parallel resonant circuit that has an inductance of 33 µH with a resistance of 14 V and a capacitance of 48 pF? 5. What value of parallel resistor is needed to set the bandwidth of a parallel tuned circuit to 1 MHz? Assume X₁ = 300, Rw = 100, and fr = 10 MHz.
