Q.2:- a) Explain what a band-pass filter is, and how it differs from either a low-pass or a high-pass filter circuit. Also, explain what a hand-stop filter is, and draw Bode plots representative of both band-pass and band-stop filter types. b) What is the purpose (ll) of the parity bit during data transmission?

-3dB point in frequency response of an active filter corresponds to  A.   absolute value negative 3dB of gain   B.   decrement of 3dB from maximum gain   C.   minimum gain attained   D.   minus 3dB of average gain value

1) A filter is used to remove the highest frequency component of the signal with the spectrum shown above. What is the minimum required sampling frequency for this new signal? 2) What if only the lowest spectrum component of this signal was required. What would be the cuttoff frequency specification of this pre-conditioning filter. What type of filter would you use for this?
