#13 Consider a standard indirect FM modulator for 94.1 FM station. The output of the NBFM stage has frequency of 200 kHz and the maximum frequency deviation of 10 Hz. Modulator is using 4 doublers and 2 tripplers after NBFM with an intermediate shifter followed by 6 more doublers. (i) (2 pts.) For the filter of the frequency shifter center frequency is most nearly: (a) 1.47 MHz) (b) 28.8 MHz (c) 12.8 MHz (d) (ii) (2 pts.) The bandwidth at end and after the last doubler is most nearly: (a) 18 KHz (b) 24 kHz (c) 48 kHz (d) 30 kHz H1A LO
