A passive antenna is an antenna that is not powered by an amplifier.
it is passive device.it is actully done.
is a thermocouple an active or passive transducer?-why?
It is passive, no amp built in or included.
A passive subwoofer doesn't have a built-in amp and will require the use of an amp.
I would not advise this, because of the difference of impedence.
It has to have resistors but an active filter will alsol have an active device, usually an op-amp, while a passive filter has only passive components and needs no power supply.
The Hartke Bass Amp is available on sites such as Amazon. Its features include passive and active inputs, rotary bass and treble contour controls and solid state preamps.
3 passive sub at 8 ohm imp in parralel will be 2.6+ impedence.Most of the professional sum amp can take up to 2 ohms load per channel(check the spec of the Amp)eg: you should be able to connect max 4 subs in each channel(match the watts pwr to amp)
It could do, which is why an op-amp is made with a very high open-loop gain so that the actual gain can be closely controlled by the passive feedback components.
Basic equipment 1.Cd players / turntables 2.Mixer 3.Speakers (Active - not needing a amp or Passive - Needing a powered amp) 4.Amp (If needed) 5.Headphones 6.Microphone 7.Wiring a) phono leads - red and white wires from CD player to mixer b)Xlr - from the mixer to the amp or speakers c)Speakon leads - from the amp to the speakers and not forgetting..... 8.Music!
Active transducers are those which require electric current (a source of energy) for working, while passive transducers are those which does not need an external source. Passive transducers directly produce electric signals without an external energy source.
from a device called signal generators or oscillators which consist of passive elements as capacitors,resistors and coils or may contain ic's as op-amp.
