How to make Low frequency clock generator using ANAD gates?

If you can see the lights flickering then there is a good chance that the frequency of the generator is low. To increase the frequency just increase the speed of the generator. On bigger diesel engines there is a knurled knob, located on the fuel rack, that can be turned up to increase the speed. If the unit has a frequency meter check to see if it is on 60 or 50 Hz depending on what country you live in. Don't depend on the frequency meter as they are not always accurate. Use a test meter that has a frequency scale and set the generator with the meters reading.
To covert a high frequency to a low one, we use flip-flops.
A frequency counter is the most accurate way. As stated above some digital multimeters include this feature, but stand alone frequency counters are also available. Another way is to use an oscilloscope and measure the period of one cycle, then calculate the frequency as the reciprocal of the period you measured. Another way is to use a multiple tuning fork frequency meter. These devices have perhaps a dozen tuning forks tuned to different frequencies (with the 60 Hz fork in the center, lower frequency forks to the left, and higher frequency forks to the right) and an electromagnetic excitation coil. The tuning fork(s) closest in frequency to the powerline will vibrate and the others will remain stationary, allowing you to read the frequency. They are a bit course in their measurement, but usually can identify differences of about 0.1 Hz. However, if your home is powered from the national power grid (not a local generator) the frequency is required to be 60 Hz to a precision that a clock synchronized to the power line will never be more then 10 seconds fast or slow of the correct time, although the line frequency might be high or low for short periods as much as a couple Hz.
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.
Another type of sine-wave generator uses inductors and capacitors for its frequency-determining network. This type is known as the LC OSCILLATOR. LC oscillators, which use tank circuits, are commonly used for the higher radio frequencies. They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
Low frequency = low pitch = long waves
