Circuit Diagram
The NE555 timer is configured as a monostable multivibrator to generate a known reference frequency. The incoming signal is compared to this reference using the NE555.
Steps for the Experiment
- Assemble the NE555 timer as a monostable multivibrator.
- Connect the frequency source to the trigger pin of the NE555.
- Measure the output frequency using an oscilloscope or frequency counter.
Explanation
The NE555 timer can be used to measure the frequency of a signal by generating pulses in response to the input frequency. These pulses are counted and compared to a reference signal.
Results and Observations
- The frequency of the incoming signal will be displayed on the oscilloscope or frequency counter.
