Digital Control Selects The Number of Analog Cycles and Burst Frequency

0 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. 1aZ04kfL.pdf (34.65 KB, 下载次数: 0 ) 0
