Abstract
The angle and amplitude modulations are two important modulation styles in the course “Radio Frequency Circuits” or “Communication Circuits”. The vector composing method is introduced in the angle modulation to analyze how the angles of carriers in the circuits of Armstrong’s PM and double-AM’s PM are modulated by signal using the vector representation. This paper discussed the similarities and differences of vector composing of AM, DSB, Armstrong’s PM and double-AM’s PM, and proved the equivalence of Armstrong’s PM and double-AM’s PM. Then a uniform vector composing circuit model had been built for these modulations using their commonness. The simulation shows that this model can save the cost of implementations and is convenient for induction analyzing, comparing with each other.
