For an Armstrong indirect FM transmitter with the crystal carrier oscillating at 210 kHz, the crystal reference oscillating at 10.2 MHz, the sideband voltage is 0.018 V, the carrier input voltage to the combiner is 5V, the first and second multipliers are both 40, and the modulating signal frequency is 2 kHz, determine: a.) modulation index at the output of the combining network and the power amplifier; b.) frequency deviation at the same two points; and c.) the transmit carrier frequency.
