International standards, such as SONET and SDH, were established to specify performance criteria for high-speed transmission of telecommunications signals over fiber-optic cables. This standardization has resulted in a number of benefits...
Fiber-optic test is an important part of building high-speed digital-communications systems. The bottom line is this: Are the bits coming across correctly? When a bit is a one, does the equipment see it as a one? When a bit is a zero, does it see...
When testing digital communication equipment, it's very useful to simulate the communication channel for various distortion effects, one of which is edge jitter. Instruments are available that will do this, but what if a simulator could be built...
Jitter problems plague many high-speed designs today, from semiconductor applications to telecommunications systems and just about everything in between. Ironically, however, when a designer wants to create jitter—perhaps to evaluate a system's...
