Microprocessor While using a frequency counter for measuring frequency, two modes of measurement are possible: Period time Frequency mode There is a ‘cross-over frequency’ below which the period mode is preferred. Assuming the crystal oscillator frequency to be 4MHz, the crossover frequency is given by 1Khz. 2 Khz. 2 Mhz. 8 Mhz. 1Khz. 2 Khz. 2 Mhz. 8 Mhz. ANSWER DOWNLOAD EXAMIANS APP
