7. We wish to design an FIR lowpass filter satisfying the specifications (1 grade) 0.98 < H(ela)< 1.02. 0< lw <0.63r, -0.15 < H(el) < 0.15, 0.657 < lwl Sn, haln] for the ideal discrete- B and M By applying a Kaiser window to the impulse response time low-pass filter with cutoff we = 0.647 required to satisfy this specification. Find the values of

Cryptography is a term used in computer science to describe secure information and communication techniques that transform messages in difficult-to-decipher ways using mathematical concepts and a set of rule-based calculations known as algorithms.
