Understanding the core principles of radio communication is essential for electronics enthusiasts, and at its heart lies the concept of modulation. This article delves into the intricacies of a frequency modulation circuit , exploring how it dynamic…
A Phase-Locked Loop (PLL) is commonly used in receiver circuits to recover and synchronize the incoming signal's phase and frequency. It is used for synchronous detection in AM receiver , FM demodulation , frequency multiplication, automatic fr…
Frequency Modulation (FM) is a widely used modulation technique in communication systems due to its resilience to noise and distortion. FM is a type of modulation that varies the frequency of a carrier signal in proportion to the amplitude of a mod…
A voltage controlled oscillator(VCO) is an electronic circuit that produces signal whose frequency is controlled by an input voltage. Thus a voltage controlled oscillator is also called voltage to frequency converter. A voltage controlled oscillato…
