← ScienceWhich outcome occurs when surface acoustic waves in interdigital transducers experience excessive parasitic capacitance?
A)Decreased signal transmission efficiency✓
B)Increased resonant operating frequency
C)Improved impedance matching bandwidth
D)Enhanced power handling capability
💡 Explanation
Signal transmission weakens because parasitic capacitance induces capacitive shunting, reducing the acoustic wave amplitude; therefore, transmission efficiency decreases, rather than increasing frequency or the power handling because of energy loss.
