Circuit Diagram Thejohnson counter circuit diagramis the cascaded arrangement of ‘n’flip-flops. In such design, the output of the proceeding flip-flop is fed back as input to the next flip-flop. For example, the inverted output of the last flip-flop ‘Q̅n’ is fed back to the firs...
respectively. The output of the first and the second event counter 36 and 38 are supplied to a control logic 40. The control logic 40 also receives a user selectable ratio number along input lines 42 which pass through a ratio select logic 44. The output of the control logic 40 is a si...
FIG. 5 is a block diagram of transponder 53 showing the functional logic thereof. As shown, the incoming signal is received at antenna 73 and coupled to R.F. demodulator 75, the output from whch is coupled to decoder 77 where an enable signal output is provided that is coupled to a di...
