                         burst sources is produced if the mean time interval between the 
                         occurrence of bursts is smaller than the average time duration of 
                         a single burst at the emission, i.e., the so-called duty cycle 
                         must be greater than one. To evaluate the background of GWs 
                         produced by an ensemble of sources, during their formation, for 
                         example, one needs to know the average energy flux emitted during 
                         the formation of a single object and the formation rate of such 
                         objects as well. In many cases the energy flux emitted during an 
                         event of production of GWs is not known in detail; only 
                         characteristic values for the dimensionless amplitude and 
                         frequencies are known. Here we present a shortcut to calculate 
                         stochastic backgrounds of GWs produced from cosmological sources. 
                         For this approach it is not necessary to know in detail the energy 
                         flux emitted at each frequency. Knowing the characteristic values 
                         for the {"}lumped{"} dimensionless amplitude and frequency we show 
                         that it is possible to calculate the stochastic background of GWs
