FOR several years past iron-cored coils for oscillatory circuits have been used by telephone engineers at audio frequencies and at the low radio frequencies which are used in carrier current telephony ...

Radio frequency inductance standard coil. A glass tube wound with cloth insulated large diameter (bell type) wire. Supported on black bakelite stand. A connecting rod is mounted on each end of the ...

“I design a radio coil. I make it with sweat and blood and it’s the ne plus ultra coil. Then I give it to a producer and tell him to make it just so. Then that bum makes it wrong. So I get into the ...

Philips India has started manufacturing radio frequency (RF) coils, used in Magnetic Resonance Imaging (MRI) systems, in the country. India has become the hub for manufacturing these MR coils for ...

Radio frequency (RF) probes designed like by microstrip patch antennas create uniform and strong magnetic field in high frequency MRI machines, unlike convention coil and bird cage shaped coils used ...

Perhaps this is one of the simplest and smallest FM radio receiver that can receive the FM stations available locally. Its simple design makes it ideal for a pocket sized FM receiver. The output of ...
