Consumer analog cassette tapes have a dynamic range of 60 to 70 dB. Analog FM broadcasts rarely have a dynamic range exceeding 50 dB. [4] The dynamic range of a direct-cut vinyl record may surpass 70 dB. Analog studio master tapes can have a dynamic range of up to 77 dB. [5]
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.
Speed units of inches per second or in/s are also abbreviated IPS. 3 + 3 ⁄ 4 in/s and 7 + 1 ⁄ 2 in/s are the speeds that were used for (the vast majority of) consumer market releases of commercial recordings on reel-to-reel tape. 3 + 3 ⁄ 4 in/s is also the speed used in 8-track cartridges. 1 + 7 ⁄ 8 in/s is also the speed used in ...
An analog signal (American English) or analogue signal (British and Commonwealth English) is any continuous-time signal representing some other quantity, i.e., analogous to another quantity. For example, in an analog audio signal , the instantaneous signal voltage varies continuously with the pressure of the sound waves .
In telecommunications, a four-wire circuit is a two-way circuit using two paths so arranged that the respective signals are transmitted in one direction only by one path and in the other direction by the other path.
Analog circuit for the dynamics of a spring-mass system (without scaling factors) Damped motion of a spring-mass system. The precision of the analog computer readout was limited chiefly by the precision of the readout equipment used, generally three or four significant figures. (Modern digital simulations are much better in this area.
Analog signal processing is a type of signal processing conducted on continuous analog signals by some analog means (as opposed to the discrete digital signal processing where the signal processing is carried out by a digital process). "Analog" indicates something that is mathematically represented as a set of continuous values.
Systematic design methods of analog and mixed-signal circuits are far more primitive than digital circuits. In general, analog circuit design cannot be automated to nearly the extent that digital circuit design can. Combining the two technologies multiplies this complication. Fast-changing digital signals send noise to sensitive analog inputs.
