How does the input impedance of a CRO affect its deflection sensitivity?
1
Lower input impedance leads to higher deflection sensitivity
2
It is directly proportional at low input impedance and inversely proportional at high input impedance
3
The input impedance does not affect deflection sensitivity
4
Higher input impedance leads to higher deflection sensitivity
