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 8 Mhz. 1Khz. 2 Khz. 2 Mhz. 8 Mhz. 1Khz. 2 Khz. 2 Mhz. ANSWER DOWNLOAD EXAMIANS APP
Microprocessor The output data lines of microprocessor and memories are usually tristated because More than one device can transmit over the data bus at the same time The data line can be multiplexed for both input and output It increases the speed of data transfer over the data bus More than one device can transmit information over the data bus by enabling only one device at a time More than one device can transmit over the data bus at the same time The data line can be multiplexed for both input and output It increases the speed of data transfer over the data bus More than one device can transmit information over the data bus by enabling only one device at a time ANSWER DOWNLOAD EXAMIANS APP
