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.
