It's rarely the microphone that's responsible for "ring at certain frequencies" and it's quite unusual to use an equalizer in front of the mixing desk. Electrete microphones have a very linear frequency response. More likely a specific microphone mount and acoustic resonators are causing the problems. Less likely a flawed amplifier circuit. It's no
Hi, The chosen high side switch has the desired "inverting" function. But it has an internal pull up current source. The voltage may go up to the input voltage. A simple TTL signal may be problematic. But there are more high side switches with logic level input. Use a online selection tool. Klaus
Provided you use the specified transistor it should be fine, its internal base resistor will limit the current to a safe level. Brian.
We are a midsize biotech organization with little/no internal Si design expertise that is likely to need outside design services for low-noise transimpedance amplifier arrays: 1000s of channels (possibly 10k's of channels in subsequent revs of the design), on as tight a pitch as reasonably possible. This will be Si-level design, with integrated D
My meters are the same. Each mA range contains a different shunt resistance. When current level is unknown I start with the highest mA range to take a reading. If the meter moves a tiny distance upscale, then I switch to a lower range. - - - Updated - - - I continue this way until I get a usable reading.
Hello All, I would like to know how the mobile knows which frequency(2G/3G/4G) it is using while communicating? for e.g. when i am moving, sometimes mobile shows it is in 3G network and sometimes in 4G Network. so i want to know when mobile network switch from 3G to 4G or vice versa, what really happens inside the mobile (hardware level)?
The 150 ohm resistance is always in the path between the op amps, thus it is the ohmic portion of the load. As for capacitors, they present zero resistance for a brief time after a change in current flow. The definition of capacitance is that it impedes a change in voltage. An op amp output has internal resistance. There may be a certain value of
like XC or some other C ProgrammerThere is the ESP-IDF toolset available that compiles in C++, however since its is not very friendly to deal even with simple applications, it is recommended only for those who are familiar with low level of programming to interface with its hardware modules. Only in the specific case of Espressif ES
You have a lot of duplicate code in there making it more difficult to read. Note that writing commands and data to the LCD only differ by the level on the RS pin so you can combine the two routines quite easily. You probably don't need the 'copyConst2Ram' routine either. Try writing a single routine, lets call it "Write2LCD(char Type, char Time,
I think you are getting a few concepts mixed up here. (I've glanced at the various data sheets but, as I've not used these devices myself, I don't have the time to study them in depth.) Taking the SPI interface first, it looks like you have this fairly well sorted if you can configure the MAX3421e registers. However you mention 'full duplex' - this
the way I interpret the rules, there are no power level limitations in ISM bands. Completely wong. There are limits for specific bands and applications, according to national (e.g FCC in the US) or regional (e.g. ETSI in Western Europe) regulations.
It's a spartan 4. The buffer outputs go to the fabric, the inputs go to top level ports.
I think ramping down the level of the original audio, switching at zero signals then ramping up the new audio is important to avoid a voltage collision POP!
What is the value and function of both v and vbar-vdd level or +vdd level. That?s all.
Specifically, you (OP) show first a flip-flop in toggle feedback configuration, but then you show a half- latch (half of a D FF) in the same feedback config and expect it to work the same (it won't, as the simulations show you). There is no such thing as a level "triggered" flip flop. You can't trigger anything deterministically by a continuous
The output remains the same irrespective of the voltage at the input Are you really sure it's an amplifier you need? Or are you asking for the output to be accurately scaled up from the voltage at the input? Or are you asking for an ALC design that takes different signal levels in and tries to give a fixed level out? Brian.
Not sure to have correctly understood you question. However let's consider to have a two port system. Connect now a generator to port 1 and a load to port 2. You will have part of the power sent to the load and some back to the generator. The power going to the load will be the input power attenuated by S21, the power coming back will be the input
1. Which mixer to choose Passive or Active? Active will give much better noise figure, that is why so popular, consumption is not a trade-off if you need -110dBm sensitivity for the receiver chain. 2. Why they use Passive mixer for I-Q demodulator in case of impedance spectroscopy in many lite
Hello, We need two stepwise ramping reference voltages from a PIC micro (as in the attached waveform). Is this possible? Originally I was going to do it with analog circuitry so I posted this????.. ..b
a raspberry is a complete linux computer. you can do a lot of user interface programming with it. it costs around $50 an arduino is a microcontroller, with a lot less power in it, and a clone can cost $3 they really are not the same devices. the arduino will be easier to interface with sensors and devices, at an electronic level the raspberry will
