Software Engineering Practice Essence of practice General steps in carrying out software engineering are, Understand the problem through communication. Plan a solution by modelling and designing. Carry out the plan (coding). Examine result for correctness (testing). Principles of best practice Software should provide value to users. Keep the software design simple. The vision of the …
What is Software? Software can be described as a collection of instruction that is executed to get desired functionalities. It is different from a program in the sense that software includes programs, documentation and operating procedures. Characteristics of software compared to hardware Software is developed, not manufactured. Does not wear out. Has reusable components. Flexible. …
Hall effect transducers can measure the magnetic field strength. Direct measurement of magnetic field intensity is impracticable and hence, this kind of transducer uses the Hall effect for this purpose. Hall effect is the production of e.m.f or voltage difference across a current-carrying conductor in the presence of a magnetic field, which is perpendicular to …
Sound is a type of energy generated from vibrations and can propagate as acoustic waves through a medium. Sound transducers convert sound energy into electrical energy or vice versa. Generally, the transducers that convert sound energy to electrical energy are input sound transducers such as microphone and those that transform electrical energy to sound are …
A photoemissive cell is also known as a phototube that operates on the photoelectric effect. It consists of a photosensitive cathode(negative) from which electrons are emitted when hit by light. It also contains an anode(positive) that attracts these free electrons. Both cathode and anode are enclosed in glass or quartz. When the electrons are drawn …
