Sinusoidal oscillator

Compact 2D schematic-style electronic block diagram of a sinusoidal oscillator. Show a rectangular amplifier block, optionally labeled A, connected in a closed positive-feedback loop with a second frequency-selective network or filter block, which may be a smaller rectangle or rounded rectangle suggesting a bandpass or resonant element. Use clean outlines, with directional arrows forming the loop, and place a small sine-wave symbol at the output to indicate steady sinusoidal output. The overall appearance should read as a generic analog electronics module or oscillator symbol rather than a detailed circuit.
