I've just started a new series of posts on my blog, www.garage-shoppe.com, for those new to SDR's. In Part I, I begin to explain how the QSD (or Tayloe detector) works by showing that a simple sample-and-hold circuit acts as a mixer. Part II will show how two or four sample and holds can be combined to form a QSD.
