Why did I learn it?
Digital processing of audio signals is still expanding in the audio industry. New, more
efficient ways of storing and transmitting sound are being developed so that you can
transmit music more quickly over the internet and so that your voice sounds more like
your voice to the person on the other end of the phone line.
Digital signal processing is also the crux of the telecommunications industry with cellular
phones and normal telephones. When you talk on the phone, your voice signal is
converted to 0s and 1s and sent via the telephone network in binary format. Your
telephone still sends and receives analog voice signals, but your voice information is A/D
and D/A converted at various points in the telephone network.
How can I apply this?
Frequency is an effective way to think about sound, but there is a myriad of other uses for
frequency counting. For example, engine speed and car speed are determined by how fast
certain moving parts on the car turn. When something rotates, each time it turns full
circle it has repeated itself. If a shaft is rotating at 100 turns per second, its frequency of
rotation is 100 Hz. Machine vibration can also be measured in terms of frequency, and so
can many metabolic signals such as breathing, heart rate, and so on.
resistors with the pushbuttons, and design them to send either high or low
signals. Hint: Review Chapter #1 for circuit and program techniques for
implementing the pushbuttons.
