For attenuation of high frequencies we can use ________(a) inductor(b)

1.	For attenuation of high frequencies we can use ________(a) inductor(b) shunt capacitance(c) series capacitance(d) combination of inductor and resistorThe question was asked in a national level competition.Question is taken from AM Wave Representation topic in chapter Amplitude Modulation of Analog Communications
Answer» Correct ANSWER is (b) shunt capacitance Best explanation: CAPACITIVE reactance, Xc is low for HIGH frequencies as Xc=(1/wC), where w is the frequency and C is the capacitance. Due to this,the high frequencies are shunted to ground and are not transmitted.
