Yes, they’re really a gift for myself, but they won’t know that. Here are some key details from the product page: Ultra-quiet mouse with 90% reduced click sound and same click feel eliminates ...
An impulse noise filter can enhance the quality of noisy signals to achieve robustness in pattern recognition and adaptive control systems. A classic filter used to remove impulse noise is the median filter, at the expense of signal degradation. Thus it's quite common to get better performing impulse noise filters with model-based systems ...
