Hi there just joined today, I was looking at the diagram of a direct conversion receiver wondering why you need an oscillator. If it oscillates at the exact same frequency as the input signal wouldn't tuner be sufficient? I can understand in a superheterodyne receiver as you need to change the frequency to an intermediate frequency. But what exactly does the local oscillator do in a direct conversion receiver?
Thanks
Pierre
