WebbSelectivity (electronic) may refer to: Selectivity (radio), a measure of the performance of a radio receiver to respond only to the radio signal it is tuned. Selectivity (circuit breakers), … Selectivity is a measure of the performance of a radio receiver to respond only to the radio signal it is tuned to (such as a radio station) and reject other signals nearby in frequency, such as another broadcast on an adjacent channel. Selectivity is usually measured as a ratio in decibels (dB), comparing the signal strength received against that of a similar signal on another frequency. If the signal is at the adjacent channel of th…

WebbWLAN RF receivers can be designed with effective ACR for narrow band signals which are approximately 0.10 the bandwidth of 802.11 signals. These narrow band signals include cordless phones and Bluetooth signals. However, wide band ACI generates significant side band energy which falls into the pass band of an 802.11 receiver. Webb(a) that the selectivity of a receiver is a measure of its ability to discriminate between a wanted signal to which the receiver is tuned and unwanted signals; (b) that economy in …

The wireless transceiver having good RF selectivity maintains good RF coverage range.

WebbReceiver selectivity is determined by various parameters in the receive chain, namely filtering, linearity, and noise. The appropriate level of selectivity needed can be quantified in terms of co-channel rejection for example. Co-channel rejection is the ratio between the desired signal to the unwanted interferer or blocker. Webb10 apr. 2024 · Selective LIS corresponds to using a subset of the total number of antennas. The algorithm employed in the selective LIS corresponds to those antennas that are placed at shorter distance from the mobile terminal. As expected, the use of selective LIS results in a performance degradation relating to the system without selective LIS.

Webb13 dec. 2024 · Fig shows the typical selectivity curve of the receiver. The selectivity depends upon tuned LC circuits used in RF and IF stages. ƒr is the resonating (tuned) frequency and Q is quality factor of these LC circuits. As shown in fig, bandwidth should be narrow for better selectivity. Hence Q of the coil should be high.
