In fact, it is a cast-away of the development in the field of radio — namely: The free-running frequency no hand near the antenna of this variable oscillator should ideally be the same as that of the fixed frequency oscillator — making the difference of these two frequencies equal to zero. Views Read Edit View history. Preset Divide By N Counter”. Phase-locked loop with VCO.

One of the oscillators is fixed and the other is coupled with the antenna to its surroundings.

For more details, please see the next ehf “Datasheet List by manufacturer”. To find out more, including how to control cookies, see here: Octal D-type transparent latch tri-state. DIP 16, SO Octal D-type flip-flop ; positive-edge trigger tri-state. The following is a list of CMOS series digital logic integrated circuits. Archived from the original on Octal bus transceiver ; tri-state outputs. The integrated circuit is fully optimized and used entirely to make a two channel system with some open options for additional hacking.

With termenvox, this usually undesirable effects were put to good use. The “datasheet” 404 countains ONLY one datasheet archive. Combining touchable pads in various manners can bring out interesting — very complex results.

Hex inverting buffer hsf by The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency. This site uses cookies. Some were built later in the vicinity of Cirkulacija 2 collective and the positive results made it perfect to develope further. Mikroelektronik in der Amateurpraxis [ Microelectronics for the practical amateur ] in German 3 ed.


The circuit has simplified oscillator sections due to use of Schmitt triggering of gates. It produces a two-channel audio output. Decade counter with decoded 7-segment display outputs and display enable. By continuing to use this website, you agree to their use. BCD 7-segment decoder, hexadecimal, active high [8]. The invention of theremin goes hand in hand with the pioneering years of radio — electronic amplification — the s.

Dual retriggerable precision monostable multivibrator with reset. Two pairs are used as variable frequency oscillators, lower and high frequencies, and third pair is used in mixed amplifying, filtering, oscillating feedback mode to play around with hwf existing pads all over the system.
