 # Question 1.1
 What happens to the Direct output signal if the terminator is not connected to the attenuated output of the pulser?
 A: To start, time scale is 400 microseconds, delta of 1.4V 
+attenuatrion switches
 normal operating shape is exponential decay after an impulse. 4V
 Now, removing attenuatrion plug. No change
 Removing the plug on the cable connected to oscilloscope, doubled magnitude of signal
