reconstruction filter, but it can also "pipeline" the stored and/or processed
data into the scope's pixel display memory. After the data has been
"backed out" of acquisition memory, the DSP block then signals the
timebase block that it can begin another acquisition.
Note that early generations of DSOs did not include an explicit Display
DSP block. This function was traditionally handled by the scope's CPU
system, but with much lower efficiency that produced much slower
waveform update rates. With custom display DSP processing, some of
today's DSOs can update waveforms as fast as 1,000,000
waveforms/second.
