Question

What are the common errors in Oscilloscope experiment, when obtaining frequency and voltage?

Answer 1

When we are doing oscilloscope experiment there could be some expertimental errors. Whch are given below

1. We get the data of voltage and frequency from the trace in the oscilloscope screen. Now during taking the reading one could get parallax error.

2. The rulings of the oscilloscope screen may not be well precised. So one could get errors in data during the time of noting the reading. This could happen when any peak comes in the mid point of two rulings of screen scale.

3. Sometimes there be present some noise. Due to which errors come in the data. Noises come mostly due to the lose connection in the connecting cables.

4. Sometimes we take the trace of ocsilloscpe screen to calculate the value of voltage and frequency. Here comes some error due to the hand drawn traces.
