TR-10 desktop analog computer of the late 1960s and early 1970s. An analog computer or analogue computer is a type of computer that uses the continuous variation aspect of physical phenomena such as electrical, mechanical, or hydraulic quantities ( analog signals) to model the problem being solved.
Analogue electronics ( American English: analog electronics) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term analogue describes the proportional relationship between a signal and a voltage or current that represents the signal.
Many models offer various types of analog modulation, either as standard equipment or as an optional capability to the base unit. This could include AM, FM, ΦM (phase modulation) and pulse modulation. A common feature is an attenuator to vary the signal’s output power. Depending on the manufacturer and model, output powers can range from − ...
Prostaglandin analogues such as misoprostol are used in treatment of duodenal and gastric ulcers. [2] Misoprostol and other prostaglandin analogues protect the lining of the gastrointestinal tract from harmful stomach acid and are especially indicated for the elderly on continuous doses of NSAIDs . In the field of ophthalmology, drugs of this ...
An analog stick ( analogue stick in British English), also known as control stick, joystick or thumbstick, is an input device for a controller (often a game controller) that is used for two-dimensional input. An analog stick is a variation of a joystick, consisting of a protrusion from the controller; input is based on the position of this ...
ΔΣM. OFDM. FDM. Multiplexing. v. t. e. Pulse-amplitude modulation ( PAM) is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulses. It is an analog pulse modulation scheme in which the amplitudes of a train of carrier pulses are varied according to the sample value of the message signal.
Pulse-density modulation, or PDM, is a form of modulation used to represent an analog signal with a binary signal.In a PDM signal, specific amplitude values are not encoded into codewords of pulses of different weight as they would be in pulse-code modulation (PCM); rather, the relative density of the pulses corresponds to the analog signal's amplitude.
Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit sample depth. Digital audio is also the name for ...
