Vamshi, I would recommend running our gr_filter_design tool. It comes installed standard with GNU Radio and allows you to view the filters you create. So look at the file of the filter you have a question about. You can replicate this filter in the filter design tool to understand it's frequency behavior. (Note that filters generated from the filter.optfir design are made using the 'equiripple' setting for the window; all other windowed filters are designed from the filter.firdes design suite).
