I am interested in applying to grad schools for MS/PhD in Electrical Engineering (signal processing is my area of focus). I have done courses and signal processing related electives in EE. However, I have no research experience in this field. The couple of projects that I have done during my undergrad are all in pure mathematics (since that was what I was earlier interested in). I will be doing my final year project in speech processing, but as of now I can't count that as 'research experience'. In the long run, I might be interested in a PhD, but can't give that sort of commitment to a new field right now. Would you suggest- (a) Getting admitted into a Masters program and then converting to PhD later (funding issues) or (b) Getting admitted into a PhD program and quitting with a Masters in case I find it too hard
