About Electronics

Electronics is a branch of physics and electrical engineering that studies electron emission, behavior, and effects using electronic devices. Electronics differs from classical electrical engineering in that it uses active devices to control electron flow via amplification and rectification, whereas classical electrical engineering only uses passive effects such as resistance, capacitance, and inductance to control electric current flow.

Electronics covers an extremely broad range of technology. Initially, the term referred to the study of electron behaviour and movement, particularly as observed in the first electron tubes. With advances in knowledge about the fundamental nature of electrons and how the motion of these particles could be utilised, it came to be used in a broader sense. Many scientific and technical disciplines now deal with various aspects of electronics. The development of key devices such as transistors, integrated circuits, lasers, and optical fibres has resulted from research in these fields. As a result, a wide range of electronic consumer, industrial, and military products can now be manufactured. Indeed, the world is in a state of flux.

Electronic systems design is concerned with the multidisciplinary design of complex electronic devices and systems such as cell phones and computers. The topic ranges from the design and development of an electronic system (new product development) to ensuring its proper function, service life, and disposal. Electronic systems design is thus the process of defining and developing complex electronic devices to meet the user’s specified requirements.

Laboratory experimentation is an important part of the development of electronic devices due to the complexity of electronics theory. These experiments are used to test or validate the engineer’s design and to identify errors. Historically, electronics labs were made up of physical electronics devices and equipment, but in recent years, the trend has shifted to electronics lab simulation software such as CircuitLogix, Multisim, and PSpice.
