11. Popular analog modulation techniques include amplitude modulation and frequency modulation. 12. The amplitude modulation comes from moving surfaces of different reflectivity and angle of reflection. 13. It broadcasts using the frequency of 1080 kHz . in the amplitude modulation band. 14. Amplitude modulation is the simplest type and the most commonly used for shortwave broadcasting.15. MultiLevel optical recording is an example of baseband pulse-amplitude modulation . 16. Additional improvements were introduced via the Quadrature Amplitude Modulation ( QAM ) encoding system. 17. Conversion to amplitude modulation is accomplished by the indicated analyzer. 18. Danelectro, Premier all produced guitar amplifiers with built-in amplitude modulation units in the late 1940s. 19. This description directly provides the two major groups of modulation, amplitude modulation and angle modulation. 20. Amplitude modulation can be operated either in the non-contact or in the intermittent contact regime.
