4.2 Logic circuits

I declare: solidlikelyshaky

1. Explain a D flip-flop and what a clock does to it; build a counter with a logic chip or a shift register.
2. Drive eight outputs from three pins with a 74HC595 and explain the timing diagram.
3. Read a datasheet timing diagram: hold time, setup time, active edge.
4. Explain the difference between a microcontroller’s RAM, flash and EEPROM and what survives a power cut.
5. Explain multiplexer, demultiplexer and decoder, and drive a seven-segment display with one of them.
6. Diagnosis: a counter that skips steps, clock bounce or setup time violation; show it on the oscilloscope.
