The set of connecting a speaker with the function generator as show in picture. When we change the frequency of the function generator, the pitch of the sound changes. When we change the amplitude of the function generator, the volume of the sound changes.
Active 2: The Vertical Voltage Axis
Connecting a tap key and battery with oscilloscope. Determine the voltage of the battery by readying the oscilloscope. First, we set the VOLTS/DIV of CH1 to 0.5V, the line show on the screen moved 3 units up when the tap key is closed. We can write a equation with this data as 3*0.5V=1.5V.
Activity 3: Lissajous Figures
This time we connected the AC Transformer to the oscilloscope on CH 1 and the Function Generator on CH 2. The function generator was set to 60 Hz and AC Transformer was set to 30Hz. When we set the oscilloscope in the XY mode we could see Lissajous Figures of the to channels.
When the function generator was set to 60 Hz and AC Transformer was set to 60Hz.
When the function generator was set to 60 Hz and AC Transformer was set to 90Hz.
When the function generator was set to 60 Hz and AC Transformer was set to 120Hz.
Activity 4: Mystery Box
We were given a mystery box and told to determine which waves or frequencies it consisted of.
