摘要： According to one embodiment, a magnetic tape drive includes a controller configured to direct first data through a first finite impulse response (FIR) gain module in response to a determination that the first data is being read from a magnetic tape medium in an asynchronous mode to control FIR gain of the first data. The controller is also configured to direct second data through a second FIR gain module in response to a determination that the second data is being read from the magnetic tape medium in a synchronous mode to control FIR gain of the second data. A FIR gain value of the second FIR gain module is automatically controlled. Other systems for dynamic gain control with adaptive equalizers are described according to more embodiments.

摘要： A system and method for suppressing jitter in a digital data signal in a signal processor system. The digital data signal has spaced apart byte allocation units wherein such spacing is increased such that unallocated bytes can be identified and removed from the digital data signal. The byte allocation units of the digital data signal are suppressed with a digital data signal being outputted from the signal processor system having suppressed byte allocation units to suppress the occurrence of jitter.
