THE FUTURE OF ELECTRONIC WASTE RECYCLING IN THE

recycling rates, 332,000 to 649,000 short tons of e-waste were recycled in the U.S. in 2010. Currently, the main driver for the recycling of e-waste is the pressure of regulatory factors. Lack of national regulation has been shown to significantly hinder recycling rates in other nations (Solving the E-waste Problem (StEP), 2009).

Active Low Pass Filter

See the above figure, In this image two op-amp cascaded with individual op-amp. In this circuit the Cascaded op amp, If the first one is having 10x gain and the second one is for 5x gain then the total gain will be 5 x 10 = 50x gain. So, the magnitude of the cascaded op-amp low pass filter circuit in case of two op-amp is:-dB = 20log(50)
