WebbThe receiver selectivity. The second quality factor concerns the selectivity of the receiver. It represents its ability to respond to a tuned station and to reject any nearby undesired signal. This is probably the first feature where your receiver will show its performance. The next one will be the DSP. Webb5 juni 2012 · Selectivity is determined by a bandpass-limiting filter and might be specified as “3 dB down at 2 kHz from center frequency and 20 dB down at 10 kHz from center frequency.” (Receiver manufacturers usually do not specify the exact bandpass shape.) Amplification. Let us consider how much amplification is needed in ordinary AM receivers.

In fact, the two main requirements of any radio receiver are that it should be able to separate one station from another, i.e. selectivity, and sensitivity so that signals can be brought to a sufficient level above the noise to be able to use the modulation applied to the carrier …

WebbR (f) is the receiver selectivity with the receiver tuned to the transmitter frequency. OFR ( f) = 10 log10 (2.3) OTR = 10 log10 (2.4) Once the FDR value has been determined for a transmitter-receiver pair, a frequency-distance separation relationship can be calculated from the following formula: LP ( f) = LR – FDR ( f) (2.5) where, WebbFig1: Selectivity.
