A radio frequency (RF) noise reduction system is disclosed to include a first antenna for receiving a RF signal, a phase shifter coupled to the first antenna for generating a phase shifted RF signal, and an amplitude detector coupled to the first antenna for outputting a signal representative of an amplitude of the RF signal. Additionally, the RF noise reduction system includes a microcontroller coupled to the amplitude detector for controlling the phase shifter. Still yet, the RF noise reduction system includes a second antenna coupled to the phase shifter and being configured to transmit the phase shifted RF signal.

System for electromagnetic interference noise reduction within an enclosure

High-speed serial communications between programmable devices connected to an I2C bus that includes a serial clock channel (SCL) and a serial data channel (SDA), having at least a logical low state and a logical high state. The programmable device determines if the SCL channel is idle, indicated by a logical high state. Determining the SCL to be idle, the programmable device holds the SCL to a logical low state. The programmable device operates high-speed serial communications using the SDA channel while holding the SCL to the low logical state. In response to completion of the high-speed communications, the programmable device releases the SCL channel and the SCL channel returns to the logical high state.
