specificity and selectivity
External environmental factors such as noise level, lighting, temperature, and distractions can influence perceptual selectivity by affecting our ability to focus on specific stimuli and filter out irrelevant information. For example, a noisy environment can increase cognitive load and reduce attention allocation, leading to decreased selectivity. Similarly, variations in lighting can impact visual perception and the ability to discern details accurately. Overall, these external factors can impact our ability to selectively attend to relevant stimuli and process information effectively.
In terms of filtration, selectivity is a parameter. It is 1 of 2 factors that determines how successful the membrane filtration process was.

perception can be defined as a process by which individual
rf is a single tuned amplifier . Its functions are :- 1.improves selectivity ( i.e rejection of unwanted signal) , so that it prevents heterodyning which results in interference frequency. 2. improves image frequency rejection 3. improves sensitivity ( gain of amplifier ) 4.improves coupling of receiver with antenna . 5. improves signal to noise ratio. 6. reradiation of local oscillator through receiver antenna is prevented

An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
