A convex function is a real-valued function defined on an interval with the property that its epigraph (the set of points on or above the graph of the function) is a convex set.
A rectifier is a electrical device that converts alternating current to direct current, a process known as rectification. Rectifiers are used as components of power supplies and as detectors of radio signals. Rectifiers may be made of solid state diodes, vacuum tube diodes, mercury arc valves, and other technologies.
A rectifier is an electronic device that changes alternating current into direct current. This process is called rectification. The three main types of rectifier are as follows-. Half-wave rectifier: It is the simplest type of rectifier, which is made with just one diode. i.When the voltage of the alternating current is positive, the diode becomes forward-biased and current flows through it. ii.he three main types of rectifier are as follows-.
