A black operation or black op is a covert or clandestine operation by a government agency, a military unit or a paramilitary organization; it can include activities by private companies or groups. Key features of a black operation are that it is secret and it is not attributable to the organization carrying it out. Such secrecy is often needed for deniability, due to the sometimes illegal or unethical nature of such operations.

A single such activity may be called a black bag operation; that term is primarily used for covert or clandestine surreptitious entries into structures to obtain information for human intelligence operations. Such operations are known to have been carried out by the FBI, CIA, KGB, Mossad, MI6, ASIS, COMANF, DGSE, AISE, CNI, MSS, R&AW, DGFI, SVR, FSB and the intelligence services of other nations.

The main difference between a black operation and one that is merely secret is that a black operation involves a significant degree of deception, to conceal who is behind it or to make it appear that some other entity is responsible (e.g. false flag operations).

In telecommunications, baseband is the range of frequencies occupied by a signal that has not been modulated to higher frequencies. Baseband signals typically originate from transducers, converting some other variable into an electrical signal. For example, the output of a microphone is a baseband signal that is an analog of the received audio. In conventional analog radio broadcasting the baseband audio signal is used, after processing, to modulate a separate RF carrier signal at a much higher frequency.

A baseband signal may have frequency components going all the way down to DC, or at least it will have a high ratio bandwidth. A modulated baseband signal is called a passband signal, which occupies a higher range of frequencies and has a much lower ratio and fractional bandwidth.
