Quadratic Time-Frequency Analysis I: Cohen's Class. Abstract: Cohen's class gathers some of the time-frequency representations which are most often used in practice. After a succinct reminder of the needs to which it tries to respond and the difficulty of responding to these needs with simple solutions, this chapter justifies
