Unformatted text preview: H d ( ω ) = R ( ω ) ej ( ωM + β ) with R ( ω ) real are called generalized linear phase . Determine whether each of the following unitpulse responses corresponds to a generalized linear phase ±lter. If so, then ±nd R ( ω ), M , and β , and indicate whether each unitpulse response corresponds to a linear phase ±lter. 1. { h ( n ) } 2 n =0 = { 2 , 1 , 2 } 2. { h ( n ) } 2 n =0 = { 1 , 2 , 3 } 1 3. { h ( n ) } 2 n =0 = {1 , 3 , 1 } 4. { h ( n ) } 4 n =0 = { 1 , 1 , 1 ,1 ,1 } 5. { h ( n ) } 3 n =0 = { , 1 , ,1 } 6. { h ( n ) } 3 n =0 = { 2 , 1 , 1 , 2 } In each case, the remaining terms of the unitpulse response of the Flter are zero. 2...
