The final stage of a class D amplfier is

A) a comparator B) a high-pass filter C) a MOSFET D) a low-pass filter

Question 2

What should be done to unused inputs on TTL gates?

A) Unused AND and NAND inputs should be tied to Vcc through a 1k-ohm resistor; unused OR and NOR inputs should be grounded.
B) All unused gates should be connected together and tied to Vcc through a 1k-ohm resistor.
C) All unused inputs should be connected to an unused output; this will insure compatible loading on both the unused inputs and unused outputs.
D) They should be left disconnected so as not to produce a load on any of the other circuits and to minimize power loading on the voltage source.
