2. Duty cycle - Wikipedia

   en.wikipedia.org/wiki/Duty_cycle

   In digital electronics, signals are used in rectangular waveform which are represented by logic 1 and logic 0. Logic 1 stands for presence of an electric pulse and 0 for absence of an electric pulse. For example, a signal (10101010) has 50% duty cycle, because the pulse remains high for 1/2 of the period or low for 1/2 of the period.

3. Raised-cosine filter - Wikipedia

   en.wikipedia.org/wiki/Raised-cosine_filter

   The raised-cosine filter is a filter frequently used for pulse-shaping in digital modulation due to its ability to minimise intersymbol interference (ISI). Its name stems from the fact that the non-zero portion of the frequency spectrum of its simplest form (=) is a cosine function, 'raised' up to sit above the (horizontal) axis.

   On a typical mission, the SR-71 took off with only a partial fuel load to reduce stress on the brakes and tires during takeoff and also ensure it could successfully take off should one engine fail. [86] Within 20 seconds the aircraft traveled 4,500 feet (1,400 m), reached 240 miles per hour (390 km/h), and lifted off.

7. 8b/10b encoding - Wikipedia

   en.wikipedia.org/wiki/8b/10b_encoding

   Because 8b/10b encoding uses 10-bit symbols to encode 8-bit words, some of the possible 1024 (10 bit, 2 10) symbols can be excluded to grant a run-length limit of 5 consecutive equal bits and to ensure the difference between the count of zeros and ones to be no more than two. Some of the 256 possible 8-bit words can be encoded in two different ...
