The basic components of the sine wave oscillation circuit include an amplifier circuit, a frequency selection network, a feedback network and an amplitude stabilizing circuit.

1. Amplification circuit: The amplification circuit is used to amplify the amplitude of the input signal of the circuit to meet the feedback conditions.

2. Frequency-selective network: The frequency-selective network is a band-pass filter that selects signals of specific frequencies and passes them to the feedback network.

3. Feedback network: The feedback network feeds back the output signal to the input end of the amplifier circuit to maintain signal oscillation.

4. Amplitude stabilization circuit: The amplitude stabilization circuit stabilizes the output of the oscillation circuit to ensure that the amplitude of the output signal is stable.

These components work together to produce a stable sine wave oscillation signal.
