In relation to a/c mains electricity, or to audio frequencies, 400 kHz is very high. In relation to radio waves it is fairly low.
The maxium frequency swing in FM is ± 75 kHz so 75 kHz x 60% = ± 45 kHz
The standard US AM band is 520 kHz-1,610 kHz. The mean would be at 1,065 kHz.
Solution Let fh is the highest frequency and fl is the lowest frequency. Bandwidth = fh - fl = 4000 - 40 KHz = 3960 KHz = 3.96 MHz
According to Niquest Theorem, it has to be more than twice the input frequency.
I came up with 14.8 khz, is this right?
Low Frequency band(30-300 kHz). It is located between VLF (Very Low Frequency) 3-30 kHz and MF (Medium Frequency) . In this band you will find Ham Radio, Time Beacons, and possibly submarines among other services.
BW = (1 MHz - 10 KHz) = (1,000 KHz - 10 KHz) = 990 KHz
freq range of rf is 3hz (extremely low frequency) to 300Ghz (extremely high frequency)
Assuming that the receiver uses a high-side local oscillator and an IF of 455 KHz, the image frequency is 910 KHz above. When tuned to 1600 KHz, the image frequency would be 2,510 KHz.
If 10 V input causes a frequency shift of 4 kHZ then 2,5v causes a freuency shift of 1 kHz. The input signal frequency of 1 kHz is irelevant.
The period of a sine wave is the reciprocal of the frequency. So, if the time period is 2.5 microseconds, the frequency would be 1 / 2.5 microseconds, which is 400 kHz.
The period of a waveform is the reciprocal of its frequency. For a clock waveform with a frequency of 500 kHz, the period can be calculated as 1 / 500 kHz = 2 microseconds.
In a 100 kHz four-stage frequency divider, each stage divides the frequency by 2. Normally, the output frequency of the fourth stage would be 100 kHz / 2^4 = 6.25 kHz. However, if the CLEAR input to stage two is LOW, it will reset stage two, preventing it from toggling and effectively stopping the division at that stage. As a result, the output frequency of the fourth stage will be 50 kHz, as only the first stage and the second stage (which is held at a constant state) are functioning.
Trovan 128 Khz and ISO 134 Khz
Period = reciprocal of frequency = 1 / (500) = 0.002 second
The frequency range of 3 kHz to 300 GHz is referred to as "radio frequency" (RF) spectrum. This range encompasses various types of electromagnetic waves used in communications, broadcasting, and radar applications. It includes subcategories like Very Low Frequency (VLF), Low Frequency (LF), Medium Frequency (MF), High Frequency (HF), Very High Frequency (VHF), Ultra High Frequency (UHF), Super High Frequency (SHF), and Extremely High Frequency (EHF).
