In telecommunications and recording, a scrambler (also referred to as a randomizer) is a device that manipulates a data stream before transmitting. The manipulations are reversed by a descrambler at the receiving side. Scrambling is widely used in satellite, radio relay communications and PSTN modems. See more In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the sender's side to make the message unintelligible at a receiver not equipped with an … See more A scrambler (or randomizer) can be either: 1. An algorithm that converts an input string into a seemingly random output string of the same length (e.g., by pseudo-randomly selecting bits to invert), thus avoiding long sequences of bits of the same value; in this … See more The first voice scramblers were invented at Bell Labs in the period just before World War II. These sets consisted of electronics that could mix two signals or alternatively "subtract" one signal back out again. The two signals were provided by a telephone and a See more Descramble in cable television context is the act of taking a scrambled or encrypted video signal that has been provided by a cable television company for premium television services, … See more Additive (synchronous) scramblers Additive scramblers (they are also referred to as synchronous) transform the input data stream by applying a pseudo-random binary sequence (PRBS) (by modulo-two addition). Sometimes a pre-calculated PRBS stored in the See more It was the need to synchronize the scramblers that suggested to James H. Ellis the idea for non-secret encryption, which ultimately led to the invention of both the RSA encryption algorithm and Diffie–Hellman key exchange well before either was … See more • Ciphony • Cryptography • Cryptochannel • One-time pad See more WebJul 9, 2008 · Description: LTE Downlink and Uplink Scrambler Library: LTE, Channel Coding Parameters Pin Inputs Pin Outputs Notes/Equations This model is used to perform downlink/uplink shared channel scrambling, user can specify the link direction by …

Jammer and Scrambler serve very different purposes. Jammer generates interference, which inhibits the ability to receive the signal. Alice transmits a signal for Bob to receive. Oscar transmits a jamming signal, which interferes with the transmission. Bob sees a reduced SNR at his receiver. Bob's ability to receive Alice's signal is suppressed. genius by stephen hawking pbs
