How To Develop Interpersonal Communication

This particular concept of communication gradually got narrowed down to various categories of which the very common are mass communication, intrapersonal communication and interpersonal communication. These categories became subjects of interest in fields of both communication and psychology and the one that the masses can identify themselves with, is interpersonal communication. The concept of interpersonal…

Acoustic Source Localisation

Performance of certain direction of arrival (DOA) estimation algorithms using a uniform linear array of scalar sensors has been analyzed and reported. Velocity hydropones, which measure one Cartesian component of the three-dimensional particle velocity vector of the incident wave field, were first reported in underwater acoustics literature in 1956. But the importance of simultanously measuring…

Why Use Prepaid Phone Cards?

Making calls locally and internationally remain to be very important. Calls are made every day, whenever you have a need to keep in touch with your friends or family, to make important business calls, to place orders or to make important enquiries. Everyone desires to have a smooth conversation from beginning to end, whether for…

The 555 Timer IC

The 555 timer IC is an incredibly useful timer that can act as either a timer or an oscillator. In timer mode, better known as monostable mode, the 555 simply acts as a “one-shot” timer; when a trigger voltage is applied to its trigger lead, the chip's output goes from low to high for a…

Metal Oxide Semiconductor Field-Effect Transistors

Metal oxide semiconductor field-effect transistors (MOSFETs) are incredibly popular transistors that in some ways resemblance JFETs. For instance, when a small voltage is applied at its gate lead, the current flow through its drain-source channel is altered. However, unlike JFETS, MOSFETs have larger gate lead input impedances (11014,, as compared with 109 for for JFETs),…

Future Communications of Mankind

Communication could be defined as passing information from one location to the other. We humans are good at communications because we developed a better tool than all other organizations on earth. That tool is language. We created languages. Languages ​​are nothing more than organized signals of messaging. Animals use sound systems but they do not…

Impedance Matching and Unmatched Impedances

Impedance Matching Since a transmission line has impedance built in, the natural question to ask is, how does the impedance affect signals that are transmitted through a transmission line from one device to another? The answer to this question ultimately depends on the impedance of the devices to which the transmission line is attached. If…

Kinds of Capacitors

There are a number of different capacitor families available, each of which has defining characteristic features. Some families are good for storing large amounts of charge yet may have high leakage currents and bad tolerances. Other families may have great tolerances and low leakage currents but may not have the ability to store large amounts…
