How Local Oscillator Drift Impacts AM Reception

Understanding Local Oscillator Drift Local oscillator drift is a phenomenon wherein the frequency of an oscillator circuit in a radio receiver unintentionally shifts over time. This drift can have significant repercussions on the performance of Amplitude Modulation (AM) reception, and it is imperative to understand the underlying mechanisms propelling this issue. Broadly, oscillator drift arises …

Understanding the Frequency Value of a Local Oscillator

Introduction to Local Oscillators A local oscillator (LO) constitutes a fundamental component within a myriad of electronic communication systems. The primary purpose of a local oscillator involves generating a signal that combines with an incoming signal to produce an intermediate frequency (IF). This intermediate frequency is notably easier to amplify and demodulate, making the processing …
