Analog electronics engineering is a specialization of electrical engineering that deals with the design and development of analog circuits. Analog circuits are used in several applications including power supplies, communications equipment, industrial control systems, and scientific instruments. Analog electronics engineers must have a thorough understanding of circuit theory and electronics components to design circuits that will work properly under a variety of conditions. They also need to be able to analyze designs for errors before building prototypes or producing commercial products using them.
Power Supply
The power supply is the device that converts alternating current (AC) to direct current (DC). A battery or an AC/DC converter can be used as a power supply. The first step in any electronics circuit is to convert the input voltage from AC to DC, so this is where we start our journey into analog electronics engineering.
Electronics Circuits
Analog electronics engineering is the study of the design and operation of electronic circuits that use passive components. In contrast to digital circuits, which use discrete signals (e.g., on or off), analog circuits use continuous values to represent information. Analogous to a water flow meter that measures volume flow rate over time, analog circuits measure voltage or current as a function of time. The term “analog” refers to any device with continuously variable properties; for example: voltage, current and resistance can be varied continuously by means of one or more control knobs in an electronic device such as a radio receiver or amplifier.
Digital Electronics
Digital electronics is the study of the theory, design and application of discrete signals and systems. It is used in computers and other devices that process information.Digital electronics is an essential part of modern engineering and can be used to build many different types of devices including:
- Computers
- Mobile phones, tablets or other portable communication devices (smartphones)
- Remote control toys such as drones, RC cars/planes/boats
Pulse Width Modulation (PWM)
Pulse Width Modulation (PWM) is a technique to control the power of a device. It is used in many applications, such as dimming LEDs, controlling motors and controlling the speed of fans. PWM can also be used in many devices such as computer fans and hard drives.
Frequency Modulation (FM)
Frequency modulation (FM) is a form of amplitude modulation that transmits information by varying the frequency of the carrier wave. The modulating signal can be an analog audio signal, a digital data stream, or an analog sinusoidal waveform.
FM was developed by Harold Edwin Armstrong in 1933, while working on his doctoral degree at Columbia University. Armstrong’s work focused on transmitting voice signals over short distances using amplitude modulation (AM), which he also invented. However, there was no need for long distance communication at this time and no commercial applications for FM radio were found until after World War II when portable radios became popular among soldiers serving overseas who wanted to hear music from home stations like WQXR in New York City or KPFA in Berkeley/Oakland California.
Degree In Analog Electronics Engineering
Analog electronics engineers design circuits and systems that control electric power and signals. They work in a wide range of industries, from telecommunications to aerospace. Analog engineers have a good understanding of digital technology as well but focus more on analog circuits and systems.
Analog engineers use tools such as transistor-based amplifiers, operational amplifiers (op amps), filters, oscillators, power supplies, electromechanical devices like relays or switches–and sometimes even vacuum tubes–to build electronic equipment like radios or computers that operate at low frequencies rather than high ones (less than 1 MHz).
Conclusion
In conclusion, it is important to understand the basics of analog electronics engineering. It can help you understand how modern technology works and make better decisions about your own personal health and safety.
