Un amplificador operacional en modo inversor.
Formula y cálculo: 
Rf = 10k
R=1k
Vout=?
Vin= 0.3vp o vpp =0.6v 

Ganancia = -(Rf/R) ó -Vout/Vin ó -Vin(Rf/R)
Ganancia = -10k/1k = -10.
Vout = G*Vin = -10*0.3 = -3vp

Observaciones:
1.- al utilizar el amp inversor ( la señal de entrada es por el negativo) la salida va estar desfasada 180 hacia atrás. 
2.- para regresarla a su estado original se deberá poner otro amplificador inversor igual con Ganancia 1. ¡Si quieren lo hago!
