1. A tuned circuit has a Q of 60 at 5 MHz. Find its bandwidth at 5 MHz and 20 MHz.
2. A receiver has a sensitivity of 0.3 µV. The same receiver can handle a signal level of 75 mV without overloading. The receiver has a blocking dynamic range of 80 dB. If the desired signal has a level of 10 µV, what is the maximum signal level that can be tolerated within the receiver passband?
3. An FM detector has a sensitivity of 50 mV/kHz. What is its maximum rms output voltage from a broadcast FM signal with a maximum deviation of 75 kHz?
4. How much stronger, in decibels, is an S-9 signal compared with an S-1 signal?
