Answer 1

This is a frequency counter. The period of the strobe pulses is known and constant (say, 2 seconds). Then the measurement cycle is as follows:
1) In the first second (t2-t3), the counter is reset to 0 and stupidly waits.
2) In the second second (t3-t4), the measured signal arrives at its input and it counts the pulses. For example, it turned out 562.
3) In the third and fourth seconds (t4-t6), the value at which the counter stopped is displayed on the indicator, and the user sees the frequency - 562 pulses per second, that is, 562 Hz. If the counting interval (item 2) was not 1 second, but different, then the decoder must convert the number of pulses into the correct frequency value in Hz.
4) The counter is then reset again and the measurement cycle is repeated.
An oscillator is a circuit that delivers a short (100 ns) pulse on the edge of an input signal. For all normal people, this is called a "one-vibrator". How it works is written here: vunivere.ru/work11278 (second scheme).
PS: A real frequency meter doesn't work that way. Or not at all.
