Audio format of the input signal. Channel. The number of source channels in the input signal (front/surround/LFE) For example, “5.1 (3/2/0.1)” means 5.1ch in total (3 front channels, 2 surround channels, and LFE). (When DTS:X content is played back) For example, “7.1.4” denotes “standard 7.1-channel plus 4 for overhead speaker ...

Therefore both the voltage across it and the current through it are representations of the audio signal. They both will change in step with the audio signal. Hopefully, if the speaker is operated in its linear region, the sound output of the speaker will also vary in step with the audio signal. \$\endgroup\$ –

MYTH: Audio Inputs and Outputs Should Be “Impedance Matched” Wastes half the signal voltage and places an unnecessarily heavy load on the driver! Transfers maximum power in vintage passive 600 Ωsystems but not applicable to modern audio systems driven by signal voltage Higher frequency cables are terminated with the “characteristic impedance” of the cable to

For a CE transistor amplifier, the audio signal voltage across the collector resistance of 2 k Ω is 2 V.Suppose the current amplification factor of the transistor is 100. The value of R B in series with V B B the supply of 2V, if the DC base current has to be 10 times the signal current is
