What is the function of a low pass filter? Draw a diagram of a simple low-pass filt using a capacitor and a resistor.

(a) Explain the function of a high pass filter. Draw a diagram of a simple high–pass filter using a capacitor and a resistor.

Q2 Design a frequency be 1000 Hz and the upper cutoff frequency be 3000 Hz and assume a sampling frequency of 8,000 Hz. Give the transfer function and the difference equation of the designed 7 tap band pass FIR filter using the frequency sampling method. Let the lower cutoff filter.

Discuss the disadvantages of increasing the order of the filter.
