Connect the TTL output (square wave) of the "Audio Oscillator" to the "Scope Selector".
Adjust the frequency of the square wave to 2 kHz. Observe and record the time domain picture, noting all the important characteristics in the graph above.
Set the maximum frequency to 24.41 kHz on the spectrum analyser. Observe and record the Frequency Domain spectrum using the PicoSoftSpectrum Analyser, noting all the important characteristics.
The relationship between cell and batteries Generally, a cell delivers a certain voltage that is a function of what chemical reactions are taking place to generate the voltage
