Wireless FM Microphone
[Abstract] High Frequency Circuit systematic introduction to communication systems,
particularly wireless communication systems and their basic function of the circuit,
given the qualitative and quantitative analysis of these methods of circuit
performance. The circuit includes a transmitter and receiver in frequency selective
amplifier, mixer circuits, power amplifier, oscillation circuit, modulation and
demodulation circuits, phase locked loop circuit, automatic gain control circuits
and frequency synthesis circuit.
The basic design of this course are: the theory and practice through teaching, so
we know when the transistors operate at high working principle, characteristics and
micro-dependent equivalent circuit parameters, frequency control circuit of the line
unit composition, the basic working principle methods, technical requirements, and
some typical IC, and have a certain theoretical level and enough of the practical
skills, communication technologies for the further study of expertise and
professional skills basis.
