Why do guitar rockers choose tube amplifiers instead of transistor amplifiers?
A: TUBE AMPLIFIERS are operating at higher voltage which makes the dynamics of amplitudes more desirable. Other then that there is no other reason. tube amplifiers are bulky heat generating components efficiency poor and frequency limited.
Which op amp is base of neural networks?
The generic op-amp would suffice for lab experiments. A number of summer amplifiers attached to a central amplifier attached to a comparator is what those at Robert Gordon University apparently use. The virtue of that design is that all those parts can be made from op-amps. Although I have not tried it, a schmitt trigger, which can also be made from op-amps, can probably be used instead of a simple comparator - making analogue ternary (three-state) logic, in other words. Cheers. For details, see http://www.rgu.ac.uk/files/chapter10%20-%20implementing%20ANNs.pdf
Instead of relying on amplifiers what did shakespeare have to use?
He used his voice, back then theatres were made to carry and project sound.
Can normal audio amplifiers can be used for guitars instead of guitar amplifiers?
I have a friend who took his car speaker and attached his amp controls to it. So yes. I have a friend who took his car speaker and attached his amp controls to it. So yes.
What is the function of ic 741 op amp?
The LM741 series are general purpose operational amplifiers which feature improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439 and 748 in most applications. The amplifiers offer many features which make their application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, as well as freedom from oscillations. The LM741C is identical to the LM741/LM741A except that the LM741C has their performance guaranteed over a 0°C to +70°C temperature range, instead of -55°C to +125°C.
What did shakespeare have to use instead of amplifiers?
Theaters were built in a certain way that helped sound carry. Also, any good actor knows how to project their voice so everyone can hear.
What is a rectifier in a guitar amp?
From Wikipedia on the subject of Tube Amplifiers...."Tube instrument amplifiers are often equipped with lower-grade transformers and simpler power regulation circuits than those of hi-fi amplifiers. They are usually not only for cost-saving reasons, but also are considered as a factor in sound creation. For example, a simple power regulation circuit's output tends to sag when there is a heavy load (that is, high output power) and vacuum tubes usually lose gain factors with lower power voltages. This results in a somewhat compressed sound which could be criticized as a "poor dynamic range" in case of hi-fi amplifiers, but could be desirable as "long sustain" of sounds on a guitar amplifier. Some tube guitar amplifiers use a rectifier tube instead of solid-state diodes specifically for this reason."
Why you use 20 log db instead of 10 log db in amplifiers?
you use 20log for voltages and 10log for power 10log(vo^2/vi^2) = 2*10log(vo/vi) = 20log(vo/vi)
How comparators works?
A comparator(electronic such as an LM393*) works by sampling two input pins and turns on an output when there is ether a difference or similarity of the inputs. it depends on how the comparator is used int he design. Say you have a reference voltage on the "inverting"( - ) pin of 5 volts. And you have the "non-inverting" ( + ) connected to measure a voltage. when the voltage on the Non-inverting side equals the inverting voltage. the Output pin will turn on. Usually the Output Pin is open and will switch to ground once the comparator is activated. Remember since most all comparators have open-collector outputs, you will need the pull-up the pin to the source voltage through a resistor to see the switching action. To make the put act differently, (instead of switching to ground when active) all you need to do is exchange(swap) the input pins. See www.national.con for a datasheet on the LM393
Why was Shockwave from Six Flags Magic Mountain placed into storage instead of being used?
Shockwave experienced a number of operational issues, which led to it being retired. The ride opened on June 3, 1988.
What are the disadvantages of using a circuit breaker instead of a fuse?
Cost is one factor but, when making a choice whether to use a circuit beraker instead of a fuse, or vice versa, there are many other technical and operational differences which have to be considered, including physical size.For more information see the answer to the Related Questionshown below.
What are the advantages of green cloud computing?
Reduced operational costs is better for the company's bottom line, and green is relatively better for the environment than traditional cloud computing. Some data centers run completely off of hydroelectric generators, for example, and so literally only costs to replace failing hardware instead of paying monthly utility fees for electricity; this both reduces operational costs and keeps the environment cleaner.
