Task №1
- determine the signal period
- choose the frequency counter operation mode. Since Тs is not included in range of measurement period, then select the mode of measuring the frequency. - determine the counting time by the formula:
- taking into account, that the counting time can take only those values (100; 101; 102; 103; 104) ms, let’s choose Тcount= 10 3 ms=1 s. - absolute error of discreteness is determined by the formula:
- relative error of discreteness:
- write the result on the display 5000.000 kHz. (Decimal point on the digital display is shifted to the left for the number of digits, which corresponds to the T count degree).

, that is 103 ms< Т count<104 ms;
