The electronic tutorials on analog and digital circuits are a great help when one is trying to grasp the concepts for practical use. However, in analog ICs, transistors are intended to amplify or produce continuously varying signals. Create one now. Analog and digital ICs contain the same basic components: primarily transistors, but also diodes and passive elements. Since the ground node is the reference for all voltages in the system, we say that logic low is 0 V. Thus, if the supply voltage for a digital circuit is 3.3 V, electrical signals present in this circuit would resemble rectangular waveforms that transition between 0 V and 3.3 V: In many applications, digital storage, transmission, and processing are so advantageous that electrical engineers employ digital techniques even when this creates a need for additional circuitry that converts analog quantities to digital quantities and then digital quantities back to analog quantities. This tutorial provides knowledge on the various modulation techniques that are useful in Analog Communication systems. A digital quantity consists of a number of discrete or discontinuous pulses whose magnitude or nature varies with time. It’s widely used in radio and audio equipment along with other applications where signals are derived from analog sensors before being converted into digital signals for subsequent storage and processing. The calculations in this system are converted into binary numbers (i.e., 1s and 0s). In binary calculations, the only available digits are one and zero, and this mathematical construct is translated into the electronic domain through the use of digital circuitry in which voltages are always “high” or “low.”. All these elements can be primarily categorized as digital, analog, or a combination of both. This is totally wrong. Our tutorial covers the basic and academic concepts that include various conversion types, decoders, multiplexers, logic gates, and many more.
