Frequency-shift keying 2 Articles . Reading Old Data Tapes, The Hard Way. October 7, 2018 by Dan Maloney 29 Comments . Those who were around for the pre-floppy days of computer mass storage were ...

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 ...

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).

More specifically, frequency-shift keying encodes information by periodically shifting the frequency of a carrier between several discrete frequencies. The company that oversees this service is ...

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 ...

By using a binary frequency shift keying (B-FSK), the audio signal frequencies can be modulated to represent binary data, aka ones and zeroes. A frequency of 18.5 kHz represents "0," while 19.5 ...

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

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 ...

Radio-frequency hack developed by researchers in Israel would let attackers steal data remotely from even air-gapped computers not connected to the internet.

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.
