Complete the following statement: If pulse 2 were superimposed on pulse 3, A) constructive interference would occur. B) the resulting pattern would be represented by 1. C) the resulting pattern would be represented by 4. D) the resulting pattern would be represented by 5. E) the resulting pattern would be different than 1, 4, and 5.

A pulse in a more dense medium is traveling towards the boundary with a less dense medium. Medium 1 Medium 2 More Dense Less Dense The partially reflected wave will be with respect to the incident wave. а. 180° in phase Ob. 180° out of phase Oc. in phase O d. 270° out of phase

Answer fast please

6. We have a signal x(n) = xa(t)]1=nT; t=nT1 where T1 7 msec, and we wish to convert x(n) to y(m) such that y(m) = xa(t)]t=mT2 with T, = 5 msec. Develop a system to do this, being sure to specify the frequency re- sponse of any filters that are used (ideal responses are okay). Are there any restrictions on xa(t) that should be imposed so that this is possible?
