radio-frequency signal

Disturbance of metal media on radio frequency signal is always influencing the effective application of RFID.

With the radio frequency identification key, the radio frequency signal can be sent outwards when a user enters a room.

RFID gains the correlation data through the radio-frequency signal automatic diagnosis target plentiful and fast.

Aerials are designed to transmit radio frequency signal between tags and readers.

The first tuner receives the first radio frequency signal and outputs a first digital signal.

sample the a second frequency of the perturbing radio-frequency signal;

The method includes: accessing the optical disc to generate a radio frequency signal;

sample the first frequency of the initial radio-frequency signal;

receive the perturbing radio-frequency signal coming from the disk;

generating a first reference signal to indicate a DC level of the radio frequency signal according to the radio frequency signal;

receive an initial radio-frequency signal coming from the disk;

generating an estimated blank signal according to the radio frequency signal;
