  2. Frequency divider - Wikipedia

    en.wikipedia.org/wiki/Frequency_divider

    A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, , and generates an output signal of a frequency: f o u t = f i n N {\displaystyle f_{out}={\frac {f_{in}}{N}}}

  3. Prescaler - Wikipedia

    en.wikipedia.org/wiki/Prescaler

    A prescaler is an electronic counting circuit used to reduce a high frequency electrical signal to a lower frequency by integer division.The prescaler takes the basic timer clock frequency (which may be the CPU clock frequency or may be some higher or lower frequency) and divides it by some value before feeding it to the timer, according to how the prescaler register(s) are configured.

  4. Voltage divider - Wikipedia

    en.wikipedia.org/wiki/Voltage_divider

    The divider output (V out) appears on the connector adjacent to the cable. A voltage divider can be used to scale down a very high voltage so that it can be measured by a volt meter. The high voltage is applied across the divider, and the divider output—which outputs a lower voltage that is within the meter's input range—is measured by the ...

  5. Crystal oscillator frequencies - Wikipedia

    en.wikipedia.org/wiki/Crystal_oscillator_frequencies

    Using frequency dividers, frequency multipliers and phase locked loop circuits, it is practical to derive a wide range of frequencies from one reference frequency. The UART column shows the highest common baud rate (under 1,000,000), assuming a clock pre-divider of 16 is resolved to an exact integer baud rate. Though some UART variations have ...

  6. Dual-modulus prescaler - Wikipedia

    en.wikipedia.org/wiki/Dual-modulus_prescaler

    Suppose that the programmable divider, using N, is only able to operate at a maximum clock frequency of 10 MHz, but the output f o is required to be in the hundreds of MHz range. Interposing a fixed prescaler that can operate at this frequency range with a division ratio M of, say, 40 drops the output frequency into the operating range of the ...

  7. Frequency-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Frequency-division...

    At the source end, for each frequency channel, an electronic oscillator generates a carrier signal, a steady oscillating waveform at a single frequency that serves to "carry" information. The carrier is much higher in frequency than the baseband signal. The carrier signal and the baseband signal are combined in a modulator circuit.

    In order to calculate the value of an annuity, you need to know the amount of each payment, the frequency of payments, the number of payments and the interest rates. To calculate the present value ...
