Question

The linear sweep for the time base in an oscilloscope has deviation from its nominal waveform. The nominal (dashed line) and actual (solid line) sweep waveforms are shown in the following figure.

A $5V$ p-p sine wave with a frequency of $1kHz$ will be measured on the oscilloscope as a sine wave with

• A. $4.45V_{p-p}and1kHzfrequency$
• B. $5V_{p-p}and1kHzfrequency$
• C. $5V_{p-p}and1.1kHzfrequency$
• D. $5V_{p-p}and1.15kHzfrequency$

Answer 1

The correct option is B $5V_{p-p}and1kHzfrequency$

It is clear from the fiigure that there is no change in amplitude.
So, it will show $5V$ peak.

$\Rightarrow$Also amplitude is function of $Y-plates$ so no change.

The frequency of the wave will seem to be same as $1kHz$.
