增加模擬電路設計出的脈沖系統效果更為理想:Repetitive pulse bursts are required for impulse testing and
for burst data transmission schemes. Impulse testing
subjects the device under test to a unit impulse or doublet,
and the response waveform is analyzed to determine the
circuit’s performance. Burst data transmission systems send
out repetitive pulse bursts. The pulse burst repetition rate is
decoded by filtering to select between different transmitting
systems, and the number of pulses in a burst form a
command. It is easy to design pulse burst systems with
digital circuits, but the results are much better when analog
circuits are used because triangular and sinewaves fit the
theory much better. Also, triangular and sinewaves incur
much less ringing and overshoot during transmission than
digital waveforms do.
