AM AND FM SIGNALS ON A OSCILLOSCOPE Why do the modulated waveforms for AM and FM appear as solid areas? Why can’t we see the individual sine wave cycles of the AM and FM carriers? The frequency of the RF carrier is much higher than that of the information signal (intelligence signal). In fact, the carrier frequency of both the AM and FM waveforms is

Unformatted text preview: 1 MHz. The information frequency is 1 kHz. Since 1 MHz is the same as 1000 kHz, 1000 cycles of carrier take place for every cycle of information . Since the oscilloscope is adjusted to show one cycle of information, it also sees 1000 cycles of carrier. The carrier sine waves blend together, forming a solid figure....
