Analog and Digital Electronics:
For this lab, we connect our phone to with the oscilloscope and a speaker, and we download the tone generator app to help to find the highest frequency that a phone can put out through the music.
In the this lab, we built the LED light circuit on the circuit board. When the power supply is on, the LED light is on. But some we find the LED light is off because LED light is a diode, when we put the power supply backward, the LED light will remain off.
Low Pass filter:
For the low pass filter lab, a circuit is set up by using a 0.1 uF capacitor, a 22K resistor, 2.2Meg, 3.3K resistor, and 0.22uF capacitor. The circuit was connected to the oscilloscope and with the tone generator app. we could find that resistors are not frequency dependents and capacitors are.
