An apparatus, method and computer program product determine (SI) channels of a television radio-band that are free of signal transmission and channels with active signal transmission.
Inputs of the signal emitting part (200, 400) are connected to outputs of the signal regenerating part (600).
The inputs of the signal emission part (200, 400) are connected to the outputs of the signal regeneration part (600).
Inputs of the signal emitting part (200, 400) are connected to outputs of the signal regenerating part (600).
The lighting device is controlled by the output of control signals of a digital control circuit (1).
A circuit (25) connected downstream of the signal emission part (200, 400) is provided for reducing the LF level when the input signal level decreases.
The transceiver sets up a connection to another transceiver by transmitting modulated signals in time slots.
Each combination includes a multi-signal transmission that comprises at least two concurrent signal transmissions from at least two antenna subarrays of N antenna subarrays and the respective location.
A group of channels immediately adjacent in the frequency domain among the channels that are free of signal transmission is selected (S2).
Due to the foregoing, degradation of the transmission characteristics of polarized multiplexed signals is suppressed and high-reliability transmission is achieved.
An apparatus and a method is provided for frequency identification and laser locking by sending optical signals of a laser through a set of optical filters.
A small number of users, such as those who perform high-speed signal transmission, capable of causing interferences to other users are selected beforehand.
It is a small terminal that can be used for one way and/or interactive communications via satellite.
Self-noise is the signal the microphone produces of itself, even when no sound source is present.
The present invention allows transmission of multiple signals between masthead electronics and base housing electronics in a base station environment.
