Function Generator Oscilloscope
An electronic test equipment used to generatedifferent types of electrical waveforms (i.e.periodical and/or modulated signals) over a widerange of frequencies.
An electronic test equipment used to measuredifferent types of electrical waveforms (i.e.periodical and/or modulated signals) over a widerange of frequencies.
Function Generator Oscilloscope
For Example:
𝐴(𝑡) = 5. sin(100𝜋𝑡)
• You can generate such a signal with 5V amplitude and 50Hz frequency usingfunction generator.
• You can measure such a signal anddetermine its amplitude frequency andtime period using an oscilloscope.
