1) An RGB color image analog phone channel with 10001000 pixel dimensions and 256 levels of each color component It is sent via a modem at 57600 bits/second. During the transmission of the color information of each pixel, a start Assume that the bit and a stop bit are added. First find out how many bits need to be sent for this color image, and then Calculate how many seconds the image can be sent. transmission without increasing the data transmission rate to send this image. What can be done to reduce the time?
