Figure 2: Frequency Modulation – continued on page 2. 1 2 Next. Modern Modulation Techniques. Jul 1, 2014 9:00 AM, Jeremy Ruck, PE. One simple form of FM is frequency-shift keying, or FSK. In FSK, ...

Frequency shift keying is robust, and has no ambiguities because one tone is higher than the other. However, phase shift keying (PSK) has many advantages in terms of efficient use of bandwidth and is ...

Digital information often must travel through analog channels in applications like satellite communication, digital cellular phones, digital microwave communication, and others. This transmission ...

The carrier frequency f (t) = f c and the amplitude a (t) = a are constant. The phase functions φ n (t) are defined over a finite period of time, i.e. t 0 ≤ t 0 + T , where T is the symbol time as ...

The peaks that are ±5 MHz away from the L1 CDMA center frequency are introduced by the binary offset carrier (BOC) modulation of the secured L1SC signal. Prominent L1SC side lobes are visible ±15, ±25 ...

His firmware reads the Binary Frequency-Shift Keying encoded data as the audio is played, then echos a checksum to prove that it works. This would be a fantastic addition to your own projects.
