excitatory frequency response area 兴奋性频率反应域
Corticofugal inhibition sharpened the frequency tuning and reduced the auditory response area of IC neurons, and corticofugal facilitation produced the opposite effects.
抑制性影响使下丘听神经元的频率调谐曲线变窄，听空间反应区域缩小，易化性影响与之相反。
It can constrain frequency response of filter Banks to form null at zero frequency point and to obtain minimum side lobe area.
它可强制滤波器组的频率特性在零频形成零点并使旁瓣面积最小。
These threedimensional geometry can be conveniently fabricated, and it has higher sensitivity on the high frequency response, that has smaller area of the junction.
