A numerically controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e., clocked), discrete-time, discrete-valued representation of a waveform, usually sinusoidal. [1] NCOs are often used in conjunction with a digital-to-analog converter (DAC) at the output to create a direct digital synthesizer (DDS). [3]
NCO is linked to the market for loanable funds and the international foreign exchange market. This relationship is often summarized by graphing the NCO curve with the quantity of country A's currency in the x-axis and the country's domestic real interest rate in the y-axis. The NCO curve gets a negative slope because an increased interest rate ...
Hexamethylene diisocyanate (HDI) is the organic compound with the formula (CH 2) 6 (NCO) 2. It is classified as an diisocyanate. It is a colorless liquid. [2] It has sometimes been called HMDI [3] but this not usually done to avoid confusion with Hydrogenated MDI.
The yellow complex Rh(PPh 3) 3 (NCO) and orange complex Rh(PPh 3) 3 (OCN) are linkage isomers and show differences in their infrared spectra which can be used for diagnosis. [15] The cyanate ion can bridge between two metal atoms by using both its donor atoms. For example, this structure is found in the compound [Ni 2 (NCO) 2 2](BPh 4) 2. In ...
A blocked isocyanate can be added to materials that would normally react with the isocyanate such as polyols.They do not react at normal ambient room temperature. A formulation containing a blocked isocyanate is a single component material (and thus usually considered more convenient) but reacts like a two-component product but will not react until heated to the temperature required for ...
Methyl isocyanate (MIC) is an organic compound with the molecular formula CH 3 NCO. Synonyms are isocyanatomethane and methyl carbylamine. Methyl isocyanate is an intermediate chemical in the production of carbamate pesticides (such as carbaryl, carbofuran, methomyl, and aldicarb). It has also been used in the production of rubbers and adhesives.
Toluene diisocyanate (TDI) is an organic compound with the formula CH 3 C 6 H 3 (NCO) 2.Two of the six possible isomers are commercially important: 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7). 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively.
Sodium cyanate is the inorganic compound with the formula NaOCN. A white solid, it is the sodium salt of the cyanate anion. ... (NCO) + CO 2 + 2NH 3 + H 2 O. Sodium ...
