What does 4 ohms mean?
It means that the loudspeaker maker tells you that his loudspeaker builds an input impedance (load impedance) of Zload = 4 to 8 ohms. In audio we use always voltage matching and so the amplifier output should have a source impedance of smaller Zsource = 0.1 ohm. Scroll down to related links and look for "Damping Factor".
What are typical values of input impedance and outoput impedance of ce amplifiers?
Output of the power amplifier is smaller 0.1 ohms and input of the loudspeaker is more than 4 ohms.
What is the principle of Impedance?
Scroll down to related links and look at "Interconnection of two units" and find the impedance picture of amplifier and loudspeaker or microphone and amplifier. Learn about "voltage bridging" - Zout < Zin.
Is it possible to use a moving coil loudspeaker instead of a moving coil microphone?
Yes, but the sensitivity and frequency response will be very poor. The diaphragm on a microphone, corresponding to the voice coil and cone on a speaker, is extraordinarily light and compliant.
Why values of modulation index greater than one are not used in full-carrier AM system?
If the modulation index is greater than 1 (more than 100% modulation) the modulated carrier signal is periodically reduced to zero. This does not effect the transmitter but at the receiver these "dead carrier" intervals result in dropouts in the audio stream from the loudspeaker producing a distorted output that is difficult to understand.
