An easy, direct evidence of the next characterization of sorts of (finitary)algebras is gifted: a cocomplete classification is reminiscent of a range iff it has an algebraic generator, i.e., a customary generator that is precisely projective and finitely generated. This improves a little a contemporary restatement, because of Pedicchio and wooden, of the classical characterization theorem of Lawvere. A bijective correspondence among algebraic theories and algebraic turbines is validated.

Photo 1c shows how the demodulated signal faithfully reproduces the DC offset and low-frequency components of the ECG. Because the sound card output is in the audible range, the modulated signal can be transmitted to the demodulator via a voice radio or telephonic link for remote signal generation. To do so, however, the tone frequencies produced by the sound card for a full-scale input must be limited to the band-pass of the communications channel. For a plain telephone line, this range is 400 Hz to 3 kHz, while a commercial FM audio link is specified to cover the 30-Hz to 15-kHz audio bandwidth.
Eightbit samples are stored as unsigned bytes, ranging from 0 to 255. Sixteenbit samples are stored as two’s-complement signed integers, ranging from –32,768 to 32,767. If you’re a Matlab user, you can avoid the hassle of file formatting by directly playing a datastream from within the Matlab environment using the sound command. wav file PCM-encoded signal into data that can be manipulated by Matlab. Another possibility is to use a professional waveform design package, such as the Pragmatic Instruments WaveWorks Pro, to create the desired signal.
