The Unit Conversion page provides a solution for engineers, translators, and for anyone whose activities require working with quantities measured in different units.Back in the day, when Firewire was a standard for any Mac, we could use Firewire to directly connect one Mac to another and transfer files at a very respectable speed – the so called “ Target Disk Mode” or “IP over Firewire”. This online unit converter allows quick and accurate conversion between many units of measure, from one system to another. In this part of the Unit Converter, we present a group of calculators related to various aspects of electrical engineering, electronics, and RF engineering. Examples of such devices are mobile phones, routers, computers, two-way radios, credit cards, satellite receivers, televisions, and other equipment that transmits and receive radio waves.
Radio-frequency engineering (RF engineering) is a field of engineering that deals with devices that transmit or receive radio waves in the radio frequency spectrum (3 kHz to 300 GHz). Internal Resistance of a Battery CalculatorĮlectrical, RF and Electronics CalculatorsĮlectronics is a branch of physics, electrical engineering, and technology concerned with the design and use of electrical circuits containing active electrical components (diodes, transistors, and integrated circuits) and passive electrical components (resistors, inductors, and capacitors) and connections between them.

We calculate the data transfer time without overhead using the following formula: Thus, we need to transmit 11 bits, which represents 100–11×100/8 = 38% overhead. The extra bits decrease the speed of the transmission and add the benefit of error-free transmission.įor example, we can add an overhead of 3 bits to send 8 bits of data. These extra bits are called overhead and this overhead can be 30% and even more. Of course, it takes more time to transmit the data because of these extra bits. These extra, redundant bits are then used to identify any errors that occur during transmission because of noise and equipment malfunction. The process of error detection and correction requires adding some extra bits to the originally transmitted data. To ensure errorless communication, various means have been developed to detect and correct bit errors. Because of these errors, data will arrive at the receiver end with errors. When binary data is transmitted over a communication link with a high speed, errors will occur because of interference, noise, or … bad contacts in the communication equipment. For example, data on a telephone twisted pair can travel at speeds up to 10 million bits per second (Mbps) and a fiber-optic cable can convey data at speeds up to 255 terabits per second over a single strand of glass fiber (as of 2021), which means 32 terabytes per second or 16 thousand 2 GB movies per second!Ī single-strand fiber-optic cable with transparent jacket used for digital audio communication Various SI decimal or binary prefixes can be added to this unit, for example: Decimal prefixesĭata transfer can take place at various speeds. It is expressed as bit per second (non-standard abbreviation bps or standard abbreviation bit/s). The speed of data transfer is determined as the number of bits transferred per unit of time and is called bit rate. For example, if each bit is transmitted over a time interval of 5 microseconds (μs), then it will take 80 μs to transmit a 16-bit Unicode letter A. A fixed interval of time is necessary to transmit each bit. Each bit of information is transmitted one after another, one bit at a time. In computing and telecommunication, data transfers are made serially over various media: wirelessly and along copper or fiber-optic cables.
