This local environment is defined as a Local area network (LAN) and connects multiple devices so the taking create store and share information with others […]

Symbol rate, Bandwidth and Bit rate definition and conversion of each other’s.

Symbol rate: In Digital Communication, the symbol rate means that the changes of symbol per second (signaling events or waveform changes) through a digital modulated signal transmission path. Symbol rate is indicate by symbols/second or baud (Bd) units. Bandwidth: Bandwidth is often used as a synonym of data transfer rate. Moving data from one point […]

Why Digital Modulation?

The digital modulation step gives the ability to provide more relevant information related to the source data. In keeping with the digital information services, higher data security, better quality communication and faster system availability are the key responsibilities of digital modulation. The Developers who observe some limitations on the communication system which are: ► Available […]

Microphone sensitivity, frequency response charts and Compression between dynamic and condenser microphones.

Microphone: A microphone is a device that converts sound or acoustic energy into electric energy. A microphone that produces a strong signal is referred to as having a higher sensitivity than one that produces a weaker signal. Sensitivity is very important for any microphone. It depends on diaphragm and its size, thickness, materiel. Microphone sensitivity […]
