Abstract: The color of a pixel produced on the face of a CRT is determined by the n bits of a hue/saturation digital input signal which is applied to a decoder to select one of 2.sup.n output lines of the decoder. Each output line is connected through a red, green and blue resistor triplet and through red, green and blue amplifier channels to respective red, green and blue signal inputs of the CRT. The values of the red, green and blue resistors in a selected resistor triplet determine the color of the pixel. The bits of a brightness signal are used to equally control the gain in the red, green and blue channels.

Abstract: A digital AM broadcast transmitter features a plurality of stages that are controlled by a digital signal representing an audio modulating signal. At least some of the stages are cascade coupled together using transformers. This reduces the need for high turns ratios and allows most or all transformers to be identical.

Abstract: Circuit includes device coupled to receive a word at its input terminals from an address bus and to gate a rearranged word from its output terminals to a data bus of a controller or processor. The word gated to the data bus has its bits interchanged by coupling each of the input terminals of the device to the output terminals corresponding to the new position of the bit in the rearranged word. The word on the address bus is distinguished from an address by specially coding the high-order lines of the address bus when the lower order lines represent the word.
