hi everyone,
iam feeling shy to ask such a small question to the great scholars,but i
must in order to complete my project.Could you please suggest me any
reference for finding information about 
1.how to design a matched filter to detect a PAM signal.
2.Is it possible to replace an equalizer with matched filter?
**I will be more thankful to you if u could give the answers as quickly as
possible.**

Usually an equalizer serves a different task than a matched filter. A matched filter is used for the detection of a certain signal while an equalizer tries to minimize the influence of the channel impulse response (whatever you can call your channel in the current application) on your transmitted signal. It depends on your current application if you need an equalizer or not.
