How do you convert low frequency to high frequency with a circuit?
You typically create a DC power supply from the low frequency, and use that to run a high frequency oscillator and amplifier. If there needs to be a relationship between frequency in and frequency out, often there is a divider running on the high frequency side in combination with a phase locked loop synching up to the low frequency side.
Frequency response of bjt amplifier?
All amplifier typically exhibit a band-pass frequency response. The cut off frequency in the low end is usually determined by the coupling band bypass capacitor .and the high frequency limit is typically determined by internal capacitances in the transistor itself.
Why high frequency is used in communication than low frequency?
High frequency is used because of the the size of antennas used to transmit and receive the communications signal. The higher the frequency the smaller the antenna.
Why dipole antenna not used for high frequency?
Depends on what you mean by high frequency. The rabbit ears antenna used in broadcast TV is a dipole and is used for VHF.
How are frequency and amplitude related?
They're not. The same amplitude can have high or low frequency, and the same frequency can have large or small amplitude.
What are the two waves that lie at the ends of the visible spectrum?
Red at the low frequency end and violet at the high frequency end.
Are X-rays are found at the high-frequency end of the electromagnetic spectrum?
.
Which color is at opposite end of a spectrum from red?
A spectrum goes from red at the low frequency end to violet at the high frequency end.
Scanner frequency Kentucky Floyd county?
There are several different scanner frequencies for Floyd County in Kentucky. The 911 dispatcher frequency is 154.80000. Law enforcement is 154.81500, 155.31000 or 155.06250.
Which light has high frequency?
The highest frequency (shortest wavelength) of visible lightis the light at the blue end of the visible spectrum.
I have two scanners. Both are programmed identical. One frequency on one of the scanners is noisy but clear on the other scanner...any ideas?
The frequency is likely a "birdie" on the second scanner -- meaning that the scanner circuitry produces a signal noise. This is common, and many scanner manuals provide a list of "birdie" frequencies.
Iowa Highway Patrol Post 1 scanner frequency?
155.640
How do you program a BC370CRS scanner?
http://www.uniden.com/pdf/BC92XLTom.pdfThe manual knows all.Straight From the Manuel:Storing Known FrequenciesInto Channels1. Press Hold. Then enter the channel number where you want to store a frequency, then press Func and Pgm. The channel number appears.2. Use the number keys and to enter the frequency (including the decimal point) you want to store.3. Press E to store the frequency into the channel. Notes:• If you entered an invalid frequency in Step 2, Error appears and the scanner beeps three times. Enter a valid frequency.• The scanner automatically rounds the entered number to the nearest valid frequency. For example, if you enter 151.473 (MHz), your scanner accepts it as 151.475.• When you enter a frequency into a channel, the scanner automatically turns on the delay function and DLY appears. When delay is turned on, the scanner automatically pauses scanning2 seconds after the end of a transmission before scanning proceeds to the next channel. To turn the function off or on, press Func + Dly.• If you enter a frequency that has already been entered elsewhere, the scanner sounds an error tone and displays the channel that was duplicated. If you entered the frequency by mis- take, press then enter the correct frequency. To enter the frequency anyway, press E to accept.4. To program the next channel in sequence, press E then repeat Steps 2 and 3.
Frequency codes for programming a cobra sr900 police scanner?
To program a Cobra SR900 police scanner, you'll need to input frequency codes for the specific services you want to monitor. Common frequency ranges for police and emergency services typically fall between 150-160 MHz for VHF and 450-470 MHz for UHF. You can find local frequency codes through online databases or scanner forums. Once you have the codes, enter them into the scanner using its keypad or programming software.
How do I delete a frequency on a Bearcat BC 147xlt?
To delete a frequency on a Bearcat BC 147XLT scanner, first, ensure the scanner is in the correct mode (e.g., frequency or channel mode). Navigate to the frequency you wish to delete using the UP/DOWN buttons. Once on the desired frequency, press and hold the "DELETE" button until you hear a confirmation beep. The frequency will be removed from the memory.
How do you program a freq of 139.21000 in bc 142xl scanner?
To program a frequency of 139.21000 MHz into a BC 142XL scanner, first turn on the scanner and press the "MANUAL" button to enter manual mode. Then, use the keypad to enter the frequency as "139210" (the MHz and kHz are implied). After inputting the frequency, press the "E" or "ENTER" button to save it. Finally, you can press the "SCAN" button to start scanning or "MANUAL" again to listen to the programmed frequency.
What does the U stand for in UHF?
Ultra high frequency.
