Direct Conversion AM Radio


Posted on Feb 7, 2014

A 0th-level attack at designing a direct conversion AM radio receiver. `Direct conversion` means we use a mixer (which just multiplies two signals) to downshift the radio frequency signal to baseband (audio) frequencies. I still don`t really know how to couple the antenna into the circuit, how to use a crystal oscillator or a mixer chip, or lots o
