a 14-bit successive approximation adc is used to sample a signal that has a full-scale range of 8V and a clock frequency of 12 MHz and a jitter of 50ns.initially this is used without a sample and hold amplifier. find the maximum signal frequency that can be sampled using this ADC. determine the maximum rate of change(in units of V/s) of the analogue input signal which can occur without impairing the conversion accuracy.
