How to Specify an Order
When ordering our products, specify them with an “Ordering Code” that consists of the following: Example : When ordering a product with model name: 2725N, frequency: 40 MHz,
overall frequency tolerance: ±100 x 10
–6
, and supply voltage: 5 V
Model name – Frequency (up to 9 digits) M – Number for specifying an order
Ordering Code: 2725N – 40.000000M – NSA6294A
If you have any queries concerning our standard frequencies and numbers for specifying orders, please contact our sales representatives or visit our homepage (http://www.ndk.com/).
Bixby 2.0 将支持智能手机、电视、冰箱、家庭扬声器已经其他互联网设备。Bixby 2.0 将采用开放设计，开发者可以选择如何与用户在服务中互动。同时，Bixby 2.0 还支持自然语言处理功能，支持更多的自然语言命令和复杂语音处理，可以真正的了解用户和家庭成员。 Bixby 作为 Siri 竞争对手，采用了与应用深度集成的方式，与其他 AI 助理，比如 Siri 和小娜不太一样。不过...[详细]
