What is a low pass filter?

One application of L-R-C series circuit is in high pass or low pass filter, which out either the low or high frequency components of a signal. A has pass filter is shown in figure where the output voltage is taken across the L-R where L-R combination represents and inductive coil that also has resistance due to the large length of the wire in the coil. which of the following statementds is correct when omega is samll in the case of V_("out")//V_(s)

A has pass filter is shown in figure where the output voltage is taken across the L-R where L-R combination represents and inductive coil that also has resistance due to the large length of the wire in the coil. Which statement is correct in the limit of large frequency is reached? (for V_("out")//V_(s))

What is meant by a high pass filter?

A : An inductor and a capacitor are called low pass filter and high pass filter respectively. R : Reactance of an inductor is low for low frequency signals and that of a capacitor is high for high frequency signals.

What is the use of a filter pump ? How does it work?

Figure shows a typical circuit for low-pass filter. An AC input V_i = 10 mV is applied at the left end and the output V_0 is received at the right end. Find the output voltages for v = 10 kHz, 100 kHz, 1.0 MHz and 10.0 MHz . Note that as the frequency is increased the output decreases and hence the name low-pass filter.
