Q2. What is physical significance of 2nd order on filtwrs
Ans. 
Second order filters have steeper roll-off and better attenuation of higher frequencies.
• Second order filters have a slope of -40 dB/decade.

• They have a higher Q factor than first order filters.

• They provide better attenuation of higher frequencies.

• Examples include Butterworth, Chebyshev, and Bessel filters.

Q1. Explain the working of CMOS inverter
Ans. 
CMOS inverter is a type of logic gate that converts input signals into their complementary outputs.
• CMOS inverter consists of a PMOS transistor and an NMOS transistor connected in series.

• When input is high, PMOS conducts and NMOS is off, resulting in output low.

• When input is low, NMOS conducts and PMOS is off, resulting in output high.

• CMOS technology is widely used in digital integrated circuits due to its low power con
