variuos sources simultaneously over a common channel by means of ’multiplexing’.For ex.‚ the bandwidth of speech signals is 3.3KHz.‚and transmitting N no.of speech signals simultaneously each of BW 3.3KHz causes interference.Hence‚to overcome this problem‚ each speech signal is modulated onto one of N carriers of frequencies 60KHz‚64KHz‚68KHz etc... I know that why we use Carrier of high frequency to send message signal over a long distance‚ when the frequency is low ‚ energy will be obviously low

BASIC DIODE ELECTRONICS INTRODUCTION TO DIODES The p-n Junction The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode‚ which can serve in electronics as a rectifier‚ logic gate‚ voltage regulator (Zener diode)‚ switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED)‚ laser diode‚ photodetector‚ or solar cell. In a relatively simplified view of semiconductor materials‚ we can envision a semiconductor as having two
