TV antennas buying guides include:Buying a TV antennaBuying TV antenna amplifier / boosterSelecting the right TV antenna for your particular television and location requires a number of things to be considered.The type of antenna - is it to be used for satellite or terrestrial, along with decisions about an internal or external antenna, antenna gain, format and many other things.
Bluetooth Tutorial / Summary Includes:Bluetooth technology basicsRadio interfaceFile transferBluetooth profilesPairing & networkingSecurityBluetooth technology is well established and is able to provide wireless connectivity for an ever increasing number of items from Bluetooth wireless headphones to mobile phone and laptop short range connectivity and wireless computer mice to many other devices requiring short range wireless connectivity.
Code Division Multiple Access, CDMA was an innovative use of direct sequence spread spectrum technology used to provide a multiple access scheme for mobile telecommunications and other wireless systems.CDMA used the property of DSSS that unless the transmitter and receiver used the same spreading code for both ends of the process, the signal could not be decoded and in this way it was able to provide a means of enabling a variety of different users to use the same channel to access a base station without mutual interference.
QSO / contact formats includes:HF QSO / contact formatMorse code QSOAmateur radio contacts can take a variety of forms on the HF ham radio bands. As a result, when starting out on the HF bands it helps to have an idea of the format for a contact and the procedures involved. In this way it is possible to converse with other ham radio operators in the most efficient and effect manner.
Smart Speakers Includes:What is a smart speakerSmart speakers have become very popular and there is a variety of smart speakers on the market from many different manufacturers.These smart speakers enable us to do a variety of different things from controlling wireless enabled lights to ordering various products and takeaways online as well as providing information like the weather forecast, time, date and many more things.
The transistor enables many circuits to be designed with a variety of different functions. From amplifiers to buffers and filters to oscillators, current sources, long tailed pairs and many, many, more.Whatever the circuit, the basic biasing conditions follow the same basic rules, but the topology of the circuit enables transistor to be used in a variety of ways to provide many different circuit functions.
