Electrical – Adding DC offset to a given input

dc-offsetoperational-amplifiervoltage

let me start off by saying I am a computer science student so I'm not familiar with electronics whatsoever. Anyway, I am faced with this problem:

I am given some input (say, a sine wave) centered on 0V (Peak to Peak is, say, -5V to 5V). I want to make my output signal with a Peak to Peak of 5V to 15V, how would I approach this? One attempt at the solution was the following circuit i got from googling – enter image description here

The circuit managed to change the DC offset but the peak to peak is not where I want it to be. Are there any other circuits I could try? I read somewhere that a non-inverting amplifier (with an op-amp) may change the offset so I will attempt that next.

Any thoughts?

Consider a clamping circuit. Such a circuit can relocate the upper or lower extreme of a waveform to a predetermined voltage level.

It sounds as if the following circuit with a 5 volt battery (or floating power supply) is what you are looking for:
