    A rectifier is an electrical device comprises of one or more diodes which allow the flow of current only in one direction.

    In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analog input terminals {displaystyle V_{+},} V_+, and {displaystyle V_{-},} V_-, and one binary digital output {displaystyle V_{
    m {o}},} {displaystyle V_{
    m {o}},}. The output is ideally

    An attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than 1.
