![]() Now we replace the switch by a potentio-meter (variable resistor). When, we move the switch from one position to other then we get an output like this Vcc, GND, Vcc, GND, Vcc, GND.This is the digital signal. It is because it has some unique advantages like noise immunity, less storage space etc.Ĭonsider a SPDT switch, Its one end connected to Vcc and other to GND. ![]() But now a days we analyse, compute, store this data only in digital or discrete form. All the physical measurements are in continuous or analog. That is, it is a continuous one and the digital is discrete one. But in digital we represent the data in all the voltages between the Vcc and GND. In digital we represent all the data in ones (high voltage level in the circuit or Vcc) and zeros (low voltage in the circuit or GND). Lets start it.ĭigital is nothing, It is only a way for communication. I believe that this experience definitely think you different. So in this instructable I made the basic digital structures like flip-flops using discrete transistors. From this we get that, The digital is only a subdivision or a limited condition of analog electronics world. The storage of digital is simple than the analog. But today we use the digital, it is only because the digital communication is simple and less interference and noisy than the analog. Basically the analog is better than the digital, because when we convert analog signal into digital its resolution decreases. The digital is a limited condition of analog. In reality the digital and analog electronics are same, the digital electronics is only a small portion of analog electronics like electronics in the physics world. So here I made this instructable to aware people which believes that digital is different from analog electronics. But what is a digital ? Is is far away from analog ? I saw many people, which believes that the digital electronics is different from analog electronics and the analog is a waste one. ![]() Now we are living in the world of digital.
