The circuit is used to indicate the relative brightness of the light striking the photocell in decimal ( 0 to 9\( ) \). The analog input voltage to the ADC is to be converted into digital form at a conversion rate of one sample per second. a) List down the required circuit(s) and component(s) and explain your choices. b) Design and sketch the circuits for the different blocks of the digital light meter. c) Explain the ADC (Analog-to-Digital) conversion process starting from the output from the photocell circuit until digit 8 is shown on the seven segment display.
