During the 1960s, HP developed many different tests and measuring devices like logic analyzers and multimeters. In order to achieve smoother interconnection between controllers and measuring instruments, the HP-IB was introduced (HP Interface Bus). HPIB is the original name for GPIB (General Purpose Interface Bus), whereas later it got many other names. Finally, the Institute of Electrical and Electronics Engineers has provided a specification number to GPIB which is 488 in the year 1978. From … [Read more...]
What is Antenna Array : Architecture & Its Applications
The antenna is the most essential component of the radio equipment and the antennas were first developed by Heinrich Hertz in the year 1888. Later on, the antennas were developed to use for long-distance applications and wireless telegraphy. Moving on with the concept of antenna, Ferdinand Braun invented the concept of antenna array by placing three monopoles in the form of a triangle. So, let's discuss more on the need for an antenna array, antenna array definition, radiation pattern, its gain, … [Read more...]
What is OR Gate : Circuit, Truth Table & Applications
We all know that logic gates are the devices that stand as functional blocks for many of the digital circuits. Nearly 90%of the electronic devices are designed with logic gates to perform logical operations in those devices. These logic gates are dependent on Boolean algebra where those will generate output depending on the combination of digital signals from the input bits. Based on the kind of logic and the inputs combinations, the result will vary. The one type of logic gate which we are … [Read more...]
