Frequency shift keying (FSK) shifts the carrier between two different frequencies called the mark and space frequencies, or f m and f s (Fig. 1c).

OOK is functionally identical to CW (Continuous Wave) that has long been used for Morse code transmissions, but at a much higher character or data rate. ASK /OOK is much cheaper and easier to ...

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.
