What is the appropriate display type (common anode/common cathode) that must be used with 7447 display decoder?Why? 2- We would like to limit the current in the LED segments to 10mA. Assuming that the turn-on voltage for the LED’s is 1.7v, what is the proper value of the resistors to be connected between the 7447 decoder and the 7-segment display? 3- Assume that the resistors provided in the lab are 220Ω. What would the current flowing into the LED’s be? 4- Design a decade counter circuit using the 7490 counter, the 7447 decoder, and a 7-segment display. Show the pin numbers on the IC’s in your design
