Week 6 HWChapter 6, problems31.) An FM broadcast-band receiver tunes from 88 to 108 MHz. The IF is 10.7 MHz, and the receiver uses high-side injection. Calculate the range of local oscillator frequencies.
40. 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?
41. A receiver has two uncoupled tuned circuits before the mixer, each with a Q of 75. The signal frequency is 100.1 MHz, and the IF is 10.7 MHz. The local oscillator uses high-side injection.(a.) Calculate the image rejection ratio in decibels. All important equations are on p.274
