CPU
To calculate the intermediate frequency (IF) for a radio receiver at 70 MHz, you typically choose a fixed IF value such as 455 kHz or 10.7 MHz. The IF frequency is chosen in such a way that when the desired signal frequency (70 MHz) is mixed with the local oscillator signal, it falls within the receiver's bandwidth for demodulation. This allows for effective filtering and processing of the signal at a manageable frequency before demodulation.
MHz. It's not technically called the FSB anymore though. It's called HyperTransport (for AMD) or QuickPath Interconnect (for Intel) these days.
The ATmega8 microcontroller can operate at a maximum frequency of 16 MHz when powered with 5V. The minimum frequency at which it can reliably function is usually around 1 MHz.
No, clock speed is not measured in bytes. Clock speed is a measure of how many cycles a computer's CPU can perform in a second, typically measured in Hertz (Hz) or gigahertz (GHz). Bytes, on the other hand, measure data size or storage capacity.
To convert from megahertz (MHz) to hertz (Hz), you would multiply the value in MHz by 1,000,000 (since 1 MHz = 1,000,000 Hz). For example, if you have a frequency of 5 MHz, you would multiply 5 by 1,000,000 to get 5,000,000 Hz.

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 most common IF in consumer FM radios is 10.7 MHz. So, for the FM broadcast band of 88 - 108 MHz, the local oscillator frequency would be between 98.7 MHz and 118.7 MHz. It could just as well have been chosen to work on the low side of the RF. But that would have placed the LO between 77.3 MHz and 97.3 MHz. Any LO leakage from the radio could have played havoc with TVs in the house tuned to the old analog Channel 5 (76 - 82 MHz) or Channel 6 (82 - 88 MHz).

Internally two crystal oscillator cycles are used as one single cycle. During one single crystal cycle it is made to logic high and logic low in next cycle so, that 50% duty cycle is maintained.
microprocessor's speed is determined by its clock rate. is normally determined by the frequency of an oscillator crystal . Typically a crystal oscillator produces a fixed sinusoidal waveform.
