TrueCrypt is a discontinued source-available freeware utility used for on-the-fly encryption (OTFE). It can create a virtual encrypted disk within a file, encrypt a partition, or encrypt the whole storage device (pre-boot authentication).
During the 1970s, the MC-2300 was an expensive piece of audio equipment, with a retail price of $1799 by the time of its discontinuation in 1980. [1] That being said, its outstanding power and sound production quality made it a valued part of many recording studios and although some people prefer the sound of tube amplifiers, the overall greater reliability and freedom from repair of the newer ...
Version Release date Significant changes 1.0 February 2, 2004 Initial release. Featured support for Windows 98, ME, 2000, and XP.Added plausible deniability for containers (although due to its simplistic nature, the practical value of the "plausible deniability" offered in this version is debatable), [1] and various bugfixes and improvements over E4M.
This method, known as a cold boot attack (which would apply in particular to a notebook computer obtained while in power-on, suspended, or screen-locked mode), was successfully used to attack a file system protected by TrueCrypt versions 4.3a and 5.0a in 2008. [32]
The Doherty amplifier is a modified class B radio frequency amplifier invented by William H. Doherty of Bell Telephone Laboratories Inc in 1936. Whereas conventional class B amplifiers can clip on high input-signal levels, the Doherty power amplifier can accommodate signals with high peak-to-average power ratios by using two amplifier circuits within the one overall amplifier to accommodate ...
The LM386 is an integrated circuit containing a low-voltage audio power amplifier. [1] It is suitable for battery-powered devices such as radios, guitar amplifiers, and hobby electronics projects. The IC consists of an 8-pin dual in-line package ( DIP-8 ) and can output 0.25 to 1 watts of power, depending on the model, using a 9-volt power supply.
A valve RF amplifier (UK and Aus.) or tube amplifier is a device for electrically amplifying the power of an electrical radio frequency signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of ...
By 1978, BGW amplifiers were installed in greater numbers in discothèques than any other amplifier. Original BGW logo. Wachner co-wrote a paper for the Audio Engineering Society (AES) in 1975, addressing the problem of differing power claims in the amplifier industry and the hope that power rating standards set by the Federal Trade Commission ...
