2. A digital clock signal is basically a square wave signal with 50% duty cycle. The frequency of the clock can be anything as needed by the digital circuit that is using it. Clock is used for timing and synchronization of digital circuits. Many times, there is a requirement to slow down the frequency of clock to a certain level and this can be done using clock frequency dividers EE200 Digital Design Laboratory Manual (reducing the frequency of clock or...
