2.52026.80

4.33521.20

4.84819.80

5.05819.40

Where:

Vpk = 27.40 vVrms = 27.40 v / Vrms = 19.37 v

Bandwidth reading of the amplifier = Frequency reading when voltage reading = Vrms.

BW= 5.058 kHz

Method 2: Rise time (Approximate)

BW = 0.35 / troseWhere: Frequency = tr (measured) = 14nstr (signal) = 4s

trose = 4sBW = 0.35 / 4sBW= 87.5 kHzIV. On the Oscilloscope:
