ECT263 Week 4 Homework Jennifer Granger Chapter 4 Review Problems 1.) What two types of modulation are included in the term angle modulation? 21) An FM signal has a deviation of 10 kHz and a modulating frequency of 2 kHz. Calculate the modulation index. 26) A 10 kHz signal modulates a 500 MHz carrier, with a modulation index of 2. What are the maximum and minimum values for the instantaneous frequency of the modulation signal? 28) A PM signal has a modulation index of 2, with a modulating signal that has an amplitude of 100 mV and a frequency of 4 kHz. What would be the effect on the modulation index of?(a) changing the frequency to 5 kHz? (b) changing the voltage to 200 mV?
