What is the difference between a high frequency UPS and a Low frequency UPS?
The difference is in sine wave generation algorithm. In HI freq - it is 30kHz signal, modulated by 50Hz.
What is frequency offset?
the difference between the source freq. and the reference freq
Advantage and disadvantage of RC coupled amplifier?
Electrical Engineering It has a wide frequence response .the gain is constant over the audio freq range which is the region of most important for speech music
What is the difference between frequency division multiplexing and freq division multiple access?
The basic difference between fdm and fdma is that fdm is used in wired system where as fdma is used in wireless communication.
What is a single tone message signal?
any signal having single frequency. ex: sin5t ,in this ex there is only 1 freq 5 rad/sec..... thats why its single tone msg signal.
What is the difference between a high frequency UPS and a Low frequency UPS?
The difference is in sine wave generation algorithm. In HI freq - it is 30kHz signal, modulated by 50Hz.
What does a toroid coil do in electronic ballast?
For oscillating low frequency current to high freq in range above 20khz so that inductor size decreases without humming noise of 50hz
Can 60hz transformer be operated at 50hz how?
As per transformer equation,E=4.44 * freq * flux * Turns.So E/ freq =Flux. So when a transformer is designed for 60Hz ,it CANNOT be operated at 50Hz and if operated may create heating effects and core saturation etc. Because E/60< E/50. However the converse condition is true i.e. a 50 HZ transformer can be used for 60Hz application Because E/50>E/60
How can IC 74190 will give output freq as 50Hz?
The 74190 is an up/down decade counter. Counters use frequency division to achieve a counting sequence. To answer your question, it depends on the input frequency. The Qa output will divide the clock input by 2 so if the input is 100Hz, Qa's output is 50Hz. Since this is a decade (0 to 9, or truncated sequence) counter and not a binary (0 to 15, or full sequence) counter, the outputs Qb, Qc and Qd divide the input but their outputs are not symmetrical (equal time high and time low). Qb and Qc produce 2 pulses for every 10 input pulses, therefore divide the input clock by 5. Qd produces one output pulse for every 10 input pulses, therefore divides the input by 10. The easiest way to visualize this is to write out the binary count in column format, starting at 0000 and ending at 1001, and looking at each of the output patterns. To produce the 50Hz output, assuming you are not concerned over symmetry: -input clock 100Hz for 50 Hz on Qa -input clock 250Hz for Qb or Qc output of 50Hz -input clock 500Hz for Qd output of 50Hz
What is the abbreviation for the word frequency?
Freq. or FREQ.
What is frequency offset?
the difference between the source freq. and the reference freq
When was Freq - album - created?
Freq - album - was created in 1984-08.
How do you calculate frequency deviation?
here is the formula modulation index=peak freq deviation/operating freq. frm this we can calculate freq dev
How do i make my bass drop low in your car?
Depending on your sub an amp set your amp freq low i would suggest under 50hz and then turn your system up and position your sub box in different areas of the boot until your happy with the sound quality
What is the number of flip flops needed to make a divide by 32 device?
6 t flip flops are needed ( to connected as in asynchronous counter), 1st t ff o/p freq will be same as i/p clk, 2nd t ff o/p freq will be half of i/p freq, and 3rd ones o/p freq is i/p freq divided by 4...... so the o/p freq of 6th ff will be i/p freq divided by 32.
How do you reference a array from one function to another?
number = myfirstfunction (text, freq); // The first function, where "text" is a string, // and "freq" is the array that is filled with data mysecondfunction (number, freq); // The 2:nd function where the value from the previous // function is being used, and the array "freq" is // bring printed.
What are the 802 standards used to specify wireless networks?
There are quite a few of them but here are the most popular: BlueTooth 802.15 Freq 2.4Ghz Speed 1Mbps WireLess Networking: 802.11a Freq 5Ghz Speed 54Mbps 802.11b Freq 2.4Ghz Speed 11Mbps 802.11g Freq 2.4Ghz Speed 54Mbps
