Talking Digital Clock Radio

摘要

An address bus of sound data, which is compounded in the main control logic(1) by an established command, is delivered to a sound composite timing circuit(41). Data is extracted in a sound data memory(5) by the address bus. A sound signal is compounded by a sound composite decoder(42), and impulse generator(Im), a noise generator(N). The sound signal and the radio output signal is changed by a control signal of a sound composite device.
