Question $4$:

a$)$ Given the following specifications:

$-7-$tap bandpass FIR filter

$-$ Lower cutoff frequency of $1500$ Hz

$-$ Upper cutoff frequency of $3000$ Hz

$-$ Sample rate of $8000$ Hz

$-$ Frequency sampling design method

$($Use the information provided in Annex$-1$ to answer this Question $4$a$.)$

$($i$)$ Determine the Transfer Function in $\backslash ($ H$($z$)\backslash )$ format $-$ Hint: Sketch the frequency response and determine the filter coefficient values.

$($ii$)$ Draw an efficient block realisation of the filter using the derived coefficient weights.

$($Give due consideration to logic area and power consumption features$)$
