... a) The conversion to decibels would be 20Log(Vout/Vin) = 20Log(2.83/1) = 9.036dB b) Vth is applied to the base and Rth is the effective resistance at this point. Vth/Rth will determine how much current available to the base. In this case, Rth = R2||R6. Vth is determined by Vcc*(R6/(R6+R2)) = Vth. c) ...

Buck converter
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
