Unformatted text preview: , by passing it through a low-pass filter whose time constant is longer than one period: τ = RC >> T = 2 π / ω Then the low pass filter output is E s cos( " t + # ) | $ / % E s cos( t + ) | / 2 / where the brackets represent averages, and the minus sign comes from the gain reversal over alternate half cycles of V ref . Show that V out = " (2 E s / )sin by doing the integrals and assuming unity gain for the amplifier...
