Digital Electronics While using a frequency counter for measuring frequency, two modes of measurement are possible. 1. Period time 2. 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 8 Mhz 1 Khz 2 Khz 2 Mhz 8 Mhz 1 Khz 2 Khz 2 Mhz ANSWER DOWNLOAD EXAMIANS APP
