Clyde Cheerman the Cheer up Robot was out and about cheering everyone up. One day he visited an elderly man.
He was confused because the elderly man said he hates computers yet he has a DAB radio and loves to listen to it.
The Elderly man says he will never use a computer but he listens to his DAB radio. All DAB radios have a computer inside them. They need a microprocessor to interpret the code that is sent in the signal.
Digital audio radio signals encode characters that describe how to assemble the sound wave. The whole signal turns off and on in timed pulses to send the code.
The elderly man was using a computer by accident. His radio is a computer that pretends to be a transistor radio.
