If a receiver has poor selectivity then it also have poor ________(a)

1.	If a receiver has poor selectivity then it also have poor ________(a) sensitivity(b) blocking of unwanted signals(c) double spotting(d) receptionThis question was posed to me in examination.The query is from Hilbert Transform in chapter Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» The correct option is (b) blocking of unwanted signals The explanation: Selectivity is the ability of a radio receiver to reject unwanted signals and ALLOW only the desired SIGNAL to pass. THUS, it’s the blocking of unwanted signals. Sensitivity is the ability of a receiver to amplify weak signals to the desired level, WHEREAS reception means to RECEIVE a signal.
