Voltage Divider Circuit and Signal Analysis on the Oscilloscope (getting hands-on with digital inputs)

Posted by SemiSaga on
Square Wave 5V Signal input giving 3.3V Square Wave Signal output at a frequency of 1kHz:


Circuit Analysis and Calculations:

Square Wave Signal Degradation at High Frequencies (MHz range): 



Voltage Divider Circuit Demonstration on the Breadboard with probes connected to Signal Generator, and Digital Storage Oscilloscope (DSO) Channel 1 = input, Channel 2 = output:



Circuit Simulation:



Now, breaking the Voltage level by Loading the circuit with a smaller Resistor (Compare Voltmeter Readings):
