History of All India Radio - DAV University


History of All India Radio Growth & Development Broadcasting in India actually began about 13 years before AIR came into existence. In June 1923 the Radio Club of Bombay made the first ever broadcast in the country. This was followed by the setting up of the Calcutta Radio Club five months later.

Understanding SWR by Example - American Radio Relay


example. In the typical ham station setup, a transmitter is connected to a feed line, which is then connected to the antenna. When you key the transmitter, it develops a radio fre-quency (RF) voltage on the transmission line input. The voltage travels down the feed line to the antenna at the other end and is called the forward wave.

Introduction to Biometric Technologies and Applications


RF Field Fingerprint Sensors • A low radio frequency (RF) signal is injected into the finger, then read by the sensor array on silicon which act like receiver antennas. • The signal strength at each antenna (or pixel) depends on the distance between the skin at that point and the sensor. This is how the image of the fingerprint is produced.
