52modulation — /moj euh lay sheuhn, mod yeuh /, n. 1. the act of modulating. 2. the state of being modulated. 3. Music. transition from one key to another. 4. Gram. a. the use of a particular distribution of stress or pitch in a construction, as the use of… …
53Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… …
54Line code — An example of coding a binary signal using rectangular pulse amplitude modulation with polar non return to zero code …
55Delta modulation — Principle of the delta PWM. The output signal (blue) is compared with the limits (green). These limits correspond to the reference signal (red), offset by a given value. Every time the output signal reaches one of the limits, the PWM signal… …
56Modified AMI code — Modified AMI codes are Alternate Mark Inversion (AMI) line codes in which bipolar violations may be deliberately inserted to maintain system synchronization. There are several types of modified AMI codes, used in various T carrier and E carrier… …
57Manchester code — In telecommunication and data storage, Manchester code (also known as Phase Encoding, or PE) is a line code in which the encoding of each data bit has at least one transition and occupies the same time. It therefore has no DC component, and is… …
58Pulse compression — is a signal processing technique mainly used in radar, sonar and echography to augment the range resolution as well as the signal to noise ratio. This is achieved by modulating the transmitted pulse and then correlating the received signal with… …
59Adaptive Coding and Modulation — (ACM) ist ein Verfahren der Datenübertragung, bei der der Empfänger eine Rückmeldung über die Qualität der empfangenen Daten gibt und darüber die Datenkodierung und Datenmodulation des Datenübertragungskanals anpasst. Beispielsweise wird ACM bei… …
