Why Use a Local Oscillator in a Radio Receiver
Introduction to Local Oscillators A local oscillator (LO) is a crucial component in the functioning of radio receivers. It is an electronic oscillator used to generate a signal with a specific frequency. The primary role of a local oscillator is to mix with the incoming signal to produce an intermediate frequency (IF), making the subsequent …
Why is the Local Oscillator Frequency Always Higher Than the Signal Frequency? Introduction to Local Oscillator and Signal Frequency In the realm of communication systems, the concepts of local oscillator (LO) frequency and signal frequency are fundamental. A local oscillator is an electronic oscillator used within both receivers and transmitters to generate a signal at …
Understanding the Local Oscillator of a Receiver Introduction to Local Oscillators In the realm of radio receivers, the local oscillator (LO) plays a critical role. A local oscillator is an electronic oscillator that generates a signal at a constant frequency. This constant frequency is crucial for the function of radio receivers, as it is mixed …
