The host communicates with the device and receives input data from the device on actions performed by the human. Output data flows from the host to the device and then to the human. The most common example of a host is a PC but some cell phones and PDAs also can be hosts. The HID protocol makes implementation of devices very simple.
With a switched mode PSU the switching frequency can be chosen to keep the noise out of the circuits working frequency band (e.g., for audio systems above the range of human hearing) Electronic noise at the input terminals. Causes harmonic distortion to the input AC, but relatively little or no high-frequency noise.
