mixing is to mistake a high-frequency signal for a low-frequency signal ,... In order to deepen our understanding of signal obfuscation, we will explain it from the spectrum perspective. The signal mixing of Time-domain waveforms is reflected in the spectrum called frequency mixing. Frequency Mixing is a special term in the signal technology. It refers to the confusion between high and low frequencies in t

Mfccs (Mel Frequency cepstral coefficents) is a widely used feature in automatic speech and speaker recognition. It was developed by Davis and Mermelstein in 1980. from that time onwards. In the field of speech recognition, Mfccs in the artificial characteristics of the

take a look at what can help improve the Wi-Fi performance of Enterprise WLAN. Disable 802.11b Data Rate In 2018, it was safe to assume that wireless devices running on your network have at least 802.11g capability. Even so, there are still many networks that allow the data rate of 802.11b, which may greatly reduce the speed of other devices connected in the 2.4 GHz band. In enterprise-level Wi-Fi hardware, it is easy to disable the 802.11b data rate. This will force wireless clients to connec
