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.
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.
How many frequency bands does the military use?
The military typically uses several frequency bands for various communication, radar, and navigation purposes. These bands can be broadly categorized into low frequency (LF), high frequency (HF), very high frequency (VHF), ultra high frequency (UHF), super high frequency (SHF), and extremely high frequency (EHF). Each band serves different operational needs, with some dedicated to secure communications, while others are used for surveillance and targeting. The exact number of frequency bands may vary based on specific military applications and technology advancements.
Which element has the most influences on the input impedance at the low and high ends of the frequency spectrum?
At low frequencies, the input impedance of a circuit is primarily influenced by capacitive elements, as they can block DC and affect the impedance seen by the input. Conversely, at high frequencies, inductive elements dominate the input impedance, as they can create high reactance and affect the circuit's performance. The interaction between these elements determines the overall frequency response, with capacitors impacting low-end behavior and inductors influencing high-end behavior.
What kind of transformer whose purpose is to combine audio frequency signals with high frequency carrier signals in a radio transmitter?
The transformer used to combine audio frequency signals with high-frequency carrier signals in a radio transmitter is called a modulation transformer. This type of transformer effectively couples the low-frequency audio signals to the high-frequency RF (radio frequency) carrier, allowing for efficient transmission of the combined signals. It ensures minimal loss and maintains the integrity of both frequency components during the modulation process.
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.
What walkie talkie frequency is police scanner?
Police scanners typically operate on frequencies within the VHF (Very High Frequency) and UHF (Ultra High Frequency) bands, specifically ranging from 30 MHz to 900 MHz, depending on the specific jurisdiction and type of communication. However, the exact frequencies can vary widely by region and agency. It's important to note that using a police scanner to monitor law enforcement communications may be subject to legal restrictions depending on local laws. Always check your local regulations before using a scanner.
Which light has high frequency?
The highest frequency (shortest wavelength) of visible lightis the light at the blue end of the visible spectrum.
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.
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.
How do you enter a frequency on a handheld uniden bearcat scanner?
To enter a frequency on a handheld Uniden Bearcat scanner, first turn on the scanner and select the appropriate mode (e.g., VHF, UHF). Press the "MAN" or "Hold" button to enter manual mode, then use the keypad to input the desired frequency. After entering the frequency, press the "E" or "Enter" button to save it to a channel. You can then press "Scan" to start searching for active transmissions on that frequency.
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.
Iowa Highway Patrol Post 1 scanner frequency?
155.640
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.
