Figure 1 : Analog vs. Digital To input nature’s analog information into digital circuits, it is first necessary to digitize the information: that is, to convert the analog signal into a digital signal. To provide a solution, first we need to understand the root cause of the problem. Digital circuits use transistors to create logic gates in order to perform Boolean logic. Although digital circuits are generally easier to design, they do tend to be a bit more expensive than an equally tasked analog circuit. Resistors follow Ohm’s law. Since this fits very well with my plans to write more about Thevenin’s Theorem, I decided to post the solution here. Each level is interpreted as one of two different states (for example, on/off, 0/1, true/false). Resistors are of two types: Fixed resistors and variable resistors.Â, In a fixed resistor, we are not able to alter the value of resistance.Â.
