Abstract
A communication device (105) includes a first communication block (205) for operation within a first communication network (150); and a second communication block (210) for operation within a second communication network (160). The communication device (105) further includes an audio control (245) for at least one microphone (250). The audio control (245) is coupled to the first communication block (205) for receiving a first audio input for operation of the first communication block (205) and is coupled to the second communication block (210) for receiving a second audio input for operation of the second communication block (210). A low noise ground (315) is isolated from a common ground (320) of the communication device (105) to facilitate the sharing of the at least one microphone (250) between the two communication blocks.
