The current pules energy created with each polarity change (almost 200 nanojoules per pulse) is sufficient to energize a low-power counter circuit
that records the rotation count.
* Bullet Impact Counter: Analog comparator based bullet-impact counter circuit was designed.
The design of bullet-impact counter circuit was reviewed and debouncer was added both in hardware and software.
The polynomial set for Johnson counter circuit in Figure 3 can be constructed as follows:
Similarly, another Johnson counter circuit with an error is shown in Figure 4, the corresponding polynomial set can be described by
Let's consider a simple 8-bit counter circuit, and, for this particular example, the design was to produce counter data that would be valid and settled prior to the rising edge of a clock.
An additional label is defined called "clock" and the proper logic analyzer clock input line is selected that has been physically attached to the counter circuit clock signal.
To achieve this, the time base circuit gets information of last digit and overflow bit from the counter circuit
The buttons are equipped with an electronic counter with LCD display, the counter circuit
In this system, active electrode, DCC and counter circuits
