5 MHz = 1 second divided by 5.000.000
4.77 MHz = 1 second divided by 4.770.000
The period of 1 MHz is 1 microsecond. The waveform is irrelevant.
477 is a not perfect square.
It is: 477/9 = 53
x + 8x = 477 9x = 477 x = 53
477 = 3 * 3 * 7
The period of 1 MHz is 1 microsecond. The waveform is irrelevant.
Let's take an example. Suppose that the intermediate frequency is 10,7 MHz (FM). The local oscillator works on 110,7 MHz. First case: You receive a signal of 100 MHz, the mixer will generate a frequency of 110,7 + 100 = 210,7 MHz, which will be rejected by the band-pass filter. The difference of the two frequencies is 110,7 - 100 = 10,7 MHz (desired one). Second case: You receive a signal of 121,4 MHz. The sum of that frequency and the local oscillator is 232,1 MHz, which will be rejected. The difference is 121,4 - 110,7 = 10,7 MHz. So the image frequency in that case is going to be 121,4 MHz.
The frequency can't be 30 Mhz 30 Mhz is a ham radio frequency but to calculate the wavelength, devide 300 by the frequency in Mhz that will give you 10 meters (300/ƒ)
A clock with a period of 1 ns has a frequency of 1 GHz, or 1000 MHz.
he rating for RIMM memory is based on the maximum theoretical bandwidth (in MHz) and included speed ratings of 800 MHz, 1066 MHz, 1200 MHz, 1333 MHz, and 1600 MHz.
477
477 is a not perfect square.
It is: 477/9 = 53
The wavelength of a frequency is the propagation speed divided by the frequency. A wave of 146 MHz, with a propagation speed of 3x108 m/s (speed of light), has a wavelength of 3x108 divided by 146x106, or about 2 m.
x + 8x = 477 9x = 477 x = 53
477 = 3 * 3 * 7
477 is a composite number. Its factors are 1, 3, 9, 53, 159, and 477.
