Apparatuses and methods for processing a digital image are provided. The bus primary energizing spring is configured to deflect toward the circuit board with a first linear displacement. The plant lacks thorns during observations to date. The emitter may comprise P+ type single crystal silicon-germanium, for example. An audio signal compressed or expanded on the time axis can be reproduced without changing the pitch by synthesizing an audio signal by an LPC synthesis filter based on the generated new predictive residual signals.
