Photo II 1.9 ν peak-peak 1
kHz sine wave displayed on an
oscilloscope having timebase
setting of 500 us/cm and vertical
attenuator setting of Vjcm
Photo 12 Square wave with fast
rise time
(
indicating good high
frequency response) and slight
sag (indicating restricted low
frequency response )
Photo 13 Square wave with
poor rise time (indicating
restricted high frequency
response) and slight sag
(indicating restricted low
frequency response )
frequency applications, 30 MHz should be considered the minimum
acceptable.
