| ■BOXCAR (ANALOG AVERAGER) N030-1014B |
|
The linear time invariant system is characterized by impulse response. If an input signal is periodic and its output signal is convolved with white noise, the N030-1014B can improve S/N by using the periodic signal synchronized with the input signal.
|
|
In the delay time Td set based on the external trigger signal ①, the N030-1014B generates the gate pulse ③ whose time width is set at Tw. Analog signals ② only within Tw charge the capacitor (integrator) with a certain time constant and its voltage is maintained until the next gate pulse srrives.
|
|
Gate pulse are continuously generated within the scan time ⑤. The integrated voltage ④ can be directly observed on an analog meter.
