Question

A vertical amplifier for a cro can be designed for

Answer 1

A vertical amplifier for a CRO can be designed for

Options:

Only a high gain  

Only a broad bandwidth

A constant gain times band-width product  

All of these

Answer 2

A vertical amplifier for a CRO can be designed for a constant gain times bandwidth product.

• The vertical amplifier is the most important factor in defining an oscilloscope's sensitivity and bandwidth.
• In general, increased sensitivity is acquired at the expense of bandwidth, as measured in V/cm of vertical deflection at the mid-band frequency.
• The vertical amplifier's gain determines the smallest signal that the oscilloscope can reproduce on the CRT screen properly.
• An oscilloscope's sensitivity is proportional to the gain of the vertical amplifier; that is, as the gain rises, sensitivity rises, allowing us to monitor signals with smaller amplitudes.
