Active filters have three main advantages over passive filters:
- Inductors can be avoided. Passive filters without inductors cannot obtain a high Q (low damping), but with them are often large and expensive (at low frequencies), may have significant internal resistance, and may pick up surrounding electromagnetic signals.
- The shape of the response, the Q (Quality factor), and the tuned frequency can often be set easily by varying resistors, in some filters one parameter can be adjusted without affecting the others. Variable inductances for low frequency filters are not practical.
- The amplifier powering the filter can be used to buffer the filter from the electronic components it drives or is fed from, variations in which could otherwise significantly affect the shape of the frequency response.

What are the advantages of using an electric guitar with active pickups over one with passive pickups?
Active pickups in an electric guitar offer advantages over passive pickups by providing a stronger output signal, reduced noise and interference, and more control over tone shaping.
What are the advantages of guitars with active pickups compared to guitars with passive pickups?
Guitars with active pickups have advantages over guitars with passive pickups in terms of higher output, clearer sound, and less interference. Active pickups use a battery-powered preamp to boost the signal, resulting in a more powerful and defined sound compared to passive pickups.
How you use 'Our' in passive voice?
Our has no bearing over whether a sentence is active or passive. It can be used in both. Active voice: A nice couple bought our house. Passive voice: Our house has been bought by a nice couple.
Is the sentence trees were bing blown over by the wind a passive voice or an active voice?
The sentence "trees were being blown over by the wind" is in passive voice because the subject (trees) is receiving the action (being blown over) rather than performing the action.
What are the benefits of using guitar active pickups compared to passive pickups?
Active pickups offer benefits such as higher output levels, reduced noise, and more control over tone shaping compared to passive pickups.
Are active 3D glasses better than the passive 3D glasses because they have battery and are more expensive that active glasses seem to be more sophisticated and reliable?
Active 3D glasses are far better than passive glasses when used with an active 3D television. Similarly, passive 3D glasses work well with passive televisions. Active glasses have been criticized for their weight in the past. Later glasses are lighter than many passive glasses, have a battery life of over one hundred hours and are proving to be exceptionally reliable.
What are the key findings from active vs passive investing studies?
Key findings from active vs passive investing studies suggest that, on average, passive investing tends to outperform active investing over the long term due to lower fees and consistent market returns. Additionally, active managers often struggle to consistently beat the market after accounting for fees and trading costs.
How does the performance of active funds compare to passive funds?
Active funds are managed by professionals who aim to outperform the market by selecting specific investments, while passive funds simply track a market index. Studies have shown that over the long term, passive funds tend to outperform active funds due to lower fees and consistent performance.
What are the advantages of active over passive guitar pickups?
*actives have less hum which to an unexperienced player they wont hear it *active pickups are easier to swap, unplug the pickup, put the other in sort of like a video game controller... no wire soldering skills required. *there are 100s of passive pickups and only few actives pros use *passive pickups are cheaper *passive require no batteries like actives *passive pickups are cheaper to swap out (less work required is the reason) *passive pickups don't sound as sterile as say EMG pickups , blackouts are more real sounding though. to reduce hum look into pickup covers and copper shielding tape
What is a passive pickup on a guitar?
Most pickups are passive but over the last several years active pickups (powered by batteries) have become popular with some players (like David Gilmour). EMG pickups are some of the more popular active pickups.
How do you change the boy pushed the tree over into passive voice?
The boys pushed the tree over. = active sentence. Boys = subject, pushed over = verb, tree = object(This sentence is a little different because it has a phrasal verb not a single word verb)To turn an active sentence into a passive sentence the object goes into the subject position =The treeNow the verb in a passive sentence is be + past participle. The verb (past tense of push over) in the active sentence = pushed over and the past participle is the same pushed over. The active sentence is a past sentence so the be verb in the passive sentence must be past = wasThe tree was pushed over. = the passive sentence. If you want to you can add the agent = the boys.The tree was pushed over by the boys. (But you don't have to add the agent).Another example:The dog chased the cat = The cat was chased. or The cat was chased (by the dog).We keep the sugar in the cupboard. = The sugar is kept in the cupboard or The sugar is kept in the cupboard by us.
What are the benefits of passive 3D glasses?
Passive glasses are lighter, and a little cheaper than active glasses. Passive glasses are under £10 whereas active glasses start at a little over $10. Passive glasses need no batteries but the resolution of passive 3D such as LG is half that of other 3D systems at just 540 lines, lower than the standard definition of 576 lines that was introduced almost 50 years ago.
