How to detect if the given signal is Data or Clock signal type?

1. What type of signal is a clock?
2. What is the difference between clock and enable signal?
3. Which device generates the clock signal?
4. What is the frequency for the clock signal?

What type of signal is a clock?

A clock signal is produced by an electronic oscillator called a clock generator. The most common clock signal is in the form of a square wave with a 50% duty cycle.

What is the difference between clock and enable signal?

A clock (better represented as clk) is a signal which is used to make the flipflop work at its positive or negative edge (in exceptional case both edge). But, an enable is a signal which makes the flipflop function as long as it is high (1). It can be made low (0) to make the flipflop stops its function.

Which device generates the clock signal?

A clock generator is an electronic oscillator that produces a clock signal for use in synchronizing a circuit's operation. The signal can range from a simple symmetrical square wave to more complex arrangements. The basic parts that all clock generators share are a resonant circuit and an amplifier.

What is the frequency for the clock signal?

Since the instruction cycle time is four clock periods, the actual timer clock frequency is 8 MHz, or the actual timer clock period is 0.125 μs.
