Which characteristics of a radio receiver refers to its ability to reject an unwanted signal?

The selectivity of an AM receiver is defined as its ability to accept or select the desired band of frequency and reject all other unwanted frequencies which can be interfering signals.

What is adjacent channel selectivity?

Adjacent Channel Selectivity (ACS) is a measure of a receiver’s ability to receive a signal at its assigned channel frequency in the presence of a strong signal in the adjacent channel.

What do you mean by selectivity?

noun. the state or quality of being selective. Electricity. the property of a circuit, instrument, or the like, by virtue of which it can distinguish oscillations of a particular frequency.

What is the difference between selectivity and sensitivity?

Sensitivity refers to a radar detector’s ability to pick up police signals at the greatest distance. Selectivity refers to the detector’s ability to filter out signals that are not true police signals, yet operate on the same frequencies as police radar (i.e. security alarms, garage doors, automatic doors, etc.).

What is the selectivity of the circuit?

The selectivity of an RLC circuit is the ability of the circuit to respond to a certain frequency and discriminate against all other frequencies. If the band of frequencies to be selected or rejected is narrow, the quality factor of the resonant circuit must be high.

What’s the definition of selectivity?

selectivity. / (sɪˌlɛkˈtɪvɪtɪ) / noun. the state or quality of being selective. the degree to which a radio receiver or other circuit can respond to and separate the frequency of a desired signal from other frequencies by tuning.

What is selectivity give an example?

The ability of the catalyst to direct the reaction to give particular products is its selectivity. For example, n-heptane in presence of platinum catalyst gives toluene.

What does the selectivity of a receiver mean?

In the other way, selectivity of the receiver means how well a receiver performs in the presence of other unwanted co-channel and adjacent channel interfering signals.

How are filters used to improve receiver selectivity?

Filters are employed in wireless/rf receiver chain to improve the selectivity of the device. The set up is slightly changed than the sensitivity setup, here one more RF signal generator is used to generate interfering signal either within the band or near the band of the desired signal.

What do you mean by spurious signal selectivity?

Read ore about Image Rejection. Spurious signal selectivity: Unwanted signals may reach the output of the radio as a result of variety of different unwanted or spurious modes. Rejecting these signals is important and it may often be contained under what may be termed spurious responses selectivity.

How does a tuned radio receiver selectivity work?

Tuned Radio Frequency, TRF, receiver : As the name implies this type of receiver relies on the filters in the RF sections of the radio to provide the selectivity. As these are variable and often at a relatively high frequency, selectivity is not as good as that provided by the superheterodyne and direct conversion receivers.
