What Is Analogue Electronics ?


The world of electronics is all about electrical circuits, electronic components, and interconnected technologies. All these elements can be primarily categorized as digital, analog, or a combination of both. However, here we will be focusing on the basics of the analog category in detail. 



Analog electronics are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels.

Analog electronics is a branch of electronics that deals with a continuously variable signal. 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. 

What is Analog ?

Analog means continuous and real. The world we live in is analog in nature, implying that it’s full of infinite possibilities. The number of smells we can sense, the number of tones we can hear, or the number of colors we can paint with; everything is infinite. The people working in the field of analog electronics are basically dealing with analog devices and circuits.

For example, if we build a circuit and it counts values like 1, 2, 3, 4, and 5; the values are neither infinite nor continuous. On the other hand, if the circuit counts like 1.00000, 1.00001, 1.00002, 4.99999, 5.00000, the amount of information would be infinite.




 If you have an analog watch, for example, it tells the time with hands that move around a dial, the position of the hands being a measurement of time. How much the hands move is directly related to what time it is. If the hour hand sweeps across two segments of the dial, it shows that twice as much time has passed compared to if it moved one segment. This sounds obvious, but it’s more subtle than it first appears, since the hand’s movements over the dial are a way of representing passing time. Basically, it’s not the same thing as time itself, but a representation or an analogy of time. This is really what the term “analog” means.

What Is Rectifier?

A  rectifier  is an electrical device composed of one or more diodes that converts alternating current (AC) to direct current (DC). A diode is like a one-way valve that allows an electrical current to flow in only one direction. This process is called rectification. A rectifier can take the shape of several different physical forms such as solid-state diodes, vacuum tube diodes, mercury arc valves, silicon-controlled rectifiers and various other silicon-based semiconductor switches. Rectifiers are used in various devices, including: DC power supplies Radio signals or detectors A source of power instead of generating current High-voltage direct current power transmission systems Several household appliances use power rectifiers to create power, like notebooks or laptops, video game systems and televisions. What is a rectifier? When the voltage is applied to the P-N junction diode in such a way that the positive terminal of the battery is connected to t...

What Is An Amplifier?

An amplifier is an electronic device that increases the voltage, current, or power of a signal. Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds.  Or Amplifier is device which increase the strength of signal. An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal. An amplifier functions by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In this sense, an amplifier modulates the output of the power supply based upon the properties of the input signal. An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss. Amplifier is made up of transistors. before invention of the transistor vacuum tubes were used in amplifier. Classification of Amplifiers 1-Type of Signal ...

Disney's 'Magic Bench' Puts You in the Picture with Animated Figures

A new "Magic Bench" designed by Disney Research lets you interact with endearing animated characters — and no special glasses or headsets are required. Instead, the complete environment — the seat, the sitter and the cartoon humanoid animals — is mirrored on a screen opposite the bench, making it possible for others to watch the scene unfold.  How does the illusion work? A camera and sensor capture images and gather depth information about physical objects — the bench and the person — that algorithms integrate with the 3D animations, the researchers wrote in a study. Meanwhile, haptic sensors built into the bench deliver vibrations that are synchronized to animated actions on the screen, creating the illusion that the animated figures are occupying real-world space next to the user.   "Our mantra for this project was: hear a character coming, see them enter the space, and feel them sit next to you," Moshe Mahler, principal digital artist at Disney R...
