1 - 4.9 Introduction to Generating FM Signals

This video introduces the two methods for generating amplitude modulated signals; direct and indirect. The direct method is simple using a Voltage Controlled Oscillator (VCO), but the indirect method was used by FM pioneers and builds on simple concepts already covered in this course. The information in this video will help you understand concepts found in "Modern Digital and Analog Communication" by B.P. Lathi and Zhi Ding.
