The Telephone About 100 years ago‚ Alexander Graham Bell invented the telephone by accident with his assistant Mr. Watson. Over many years‚ the modern version of the telephone makes the one that Bell invented look like a piece of junk. Developments in tone dialing‚ call tracing‚ music on hold‚ and electronic ringers have greatly changed the telephone. This marvelous invention allows us to communicate with the entire globe 24 hours a day just by punching in a simple telephone number. It is the

Recent work on tumor detection employs ultrasonic waves and echo-ranging techniques with cathode-ray presentation. the pulses are sent into the body and the echos return in different intensities depending upon the difference in acoustical impedance of the malignant and nonmalignant tissues and in different times depending upon the depths of the reflecting boundaries. A small version of the ultrasonic drill has been developed for use by dentists in drilling teeth. the advantages of the ultrasonic

the resistances‚ which dissipate the power and energy storing elements such as capacitances and inductances are known as passive elements. The transformers may be regarded as a matching device. The success of any electronic circuit depends not only on proper selection of the active elements but on the passive and matching elements too. The proper function‚ of an active device is decided by the proper values of these passive elements. Hence the selection of these elements such as resistances‚ inductances
