The crucial difference between LED and OLED is that LED does not work on the principle of self-illumination as it needs a backlight for its operation. As against OLED is a self-illuminating type device as it does not require a backlight in order to initiate its operation. Another major difference between LED and OLED is that a wider viewing angle is noticed in the case of OLED. At the same time, black level is more dominant in OLED as compared to LED. We will discuss some more important … [Read more...] about Difference Between LED and OLED

The crucial difference between CRT and LCD exist in their image forming technique. CRT displays image on the screen by making use of electron beam, however, LCD utilizes liquid crystals for the formation of an image on the screen. Another major difference that exists between CRT and LCD is their size and dimension. CRT monitors are thicker and heavier but small in size than that of LCD. We will discuss some other important differences between CRT and LCD but before that have a look at the … [Read more...] about Difference Between CRT and LCD

The crucial difference between copper cable and fiber optics is that copper cable transmits signal in the form of electrical pulses while fiber optics possess signal transmission in the form of light pulses. Another major difference between copper cable and fiber optics lies in their name itself. A copper cable is made of copper wire. As against fiber optics is formed by single or multiple strands of glass fiber. Before proceeding further, have a look at the rough draft towards the … [Read more...] about Difference Between Copper Cable and Fiber Optics

The major difference between modulation and demodulation is that modulation is the act of altering the parameters of the carrier signal according to message signal for convenient data transmission. On the contrary, demodulation is done in order to recover the original message signal from a modulated signal. Another crucial difference between modulation and demodulation is that modulation is done at the transmitting end while demodulation occurs at the receiving end. Both modulation and … [Read more...] about Difference Between Modulation and Demodulation

Both encoder and decoder are combinational logic circuits, however, one of the crucial difference between encoder and decoder is that an encoder provides binary code as its output. On the contrary, a decoder accepts binary code as its input. An encoder is a device that converts the active data signal into a coded message format. However, a decoder performs inverse operation of the encoder and thus converts the coded input into original data input. In order to have secured data … [Read more...] about Difference Between Encoder and Decoder

The major difference between active and passive transducer is that an active transducer has the ability to convert one form of energy into another form (electrical) without using an external source of power. On the contrary, a passive transducer converts a form of energy into another (electrical) by making use of an external source of power. Active transducers are also known as self-generating transducers while passive transducers are known as externally energized transducers. We will … [Read more...] about Difference Between Active and Passive Transducer

The working principle of both Photodiode and Phototransistor is same however, various factors differentiate the two. The major difference between photodiode and phototransistor is their current gain. In other words, we can say, a phototransistor produces more current as compared to the photodiode when exposed to the same amount of light energy. Another crucial difference between photodiode and phototransistor is that a normal PN junction diode is employed in a photodiode that produces an … [Read more...] about Difference Between Photodiode and Phototransistor

The major factor that differentiates multiplexer and demultiplexer is their ability to accept multiple input and single input respectively. The multiplexer also known as a MUX operates on several inputs but provide a single output. As against demultiplexer also known as DEMUX simply reverses the operation of MUX and operates on single input but transmits the data to multiple outputs. It is noteworthy here that multiplexer acts as data selector thus provide a single output from several inputs. … [Read more...] about Difference Between Multiplexer (MUX) and Demultiplexer (DEMUX)
