If the error in delay is defined as Tg(ωk)- Tg(ω0)- Td(ωkk), then what is Tg(ω0)?
A. Filter delay at nominal frequency in stop band
B. Filter delay at nominal frequency in transition band
C. Filter delay at nominal frequency
D. Filter delay at nominal frequency in pass band
Answer:A
If the error in delay is defined as Tg(ωk)- Tg(ω0)- Td(ωkk), then what is Tg(ω0)?
A. Filter delay at nominal frequency in stop band B. Filter delay at nominal frequency in transition band C. Filter delay at nominal frequency D. Filter delay at nominal frequency in pass band
Explanation: We are led to define the error in delay as Tg(ωk)- Tg(ω0)- Td(ωk), where Tg(ω0) is the filter delay at some nominal centre frequency in the pass band of the filter.
