If h(n) has finite energy and h(n)=0 for n<0, then which of the following are true?
If |H(ω)| is square integrable and if the integralis finite, then the filter with the frequency response
The magnitude function |H(ω)| can be zero at some frequencies, but it cannot be zero over any finite band of frequencies.
If h(n) is causal and h(n)=he(n)+ho(n),then what is the expression for h(n) in terms of only he(n)?
If h(n) is causal and h(n)=he(n)+ho(n),then what is the expression for h(n) in terms of only ho(n)?
If h(n) is absolutely summable, i.e., BIBO stable, then the equation for the frequency response H(ω) is given as?
HR(ω) and HI(ω) are interdependent and cannot be specified independently when the system is causal.
