Abstract: PROBLEM TO BE SOLVED: To provide a circuit whose quality is satisfactory by generating high pass frequency signal components corresponding to a picture element under consideration, and adding them to the picture element under consideration, and amplitude-limiting the signal level of the added output between an upper limit value and a lower limit value. SOLUTION: The output of a high pass filter HPF: 8 is inputted to a multiplier 9, and a signal B2 is outputted, and inputted to an adder 10. The adder 10 adds a signal B1 and the signal B2, and outputs a signal B5. The signal B5 is a signal obtained by adding high pass frequency signal components to the signal B1, and this signal B5 is inputted to a maximum value detecting circuit MAX: 11. The MAX: 11 selects the larger one among the signals 4 and 5, and outputs a signal B6. The undershoot part of the signal B5 is removed by the MAX: 11. The signal B6 is inputted to the minimum value detecting circuit MIN: 12. The MIN: 12 selects the smaller one among the signals B3 and B6, and outputs a signal B7. The overshoot part of the signal B6 is removed by the MIN: 12.

Title: And circuit
Inventor: HATSUDA TSUGIYASU
IPC: H03K19/08
Filed: 1990-06-11
Abstract: PURPOSE:To accelerate a switching operation by controlling the switching of an NPN transistor (TR) with an inverted input signal and ON/OFF of a multi-input N-channel MOSFET array. CONSTITUTION:In the case of a 1st signal at a low level L, a drain level is set to a high level H by a P-channel MOSFET 110. When 1st - n-th signals go to an H level, a power is supplied to the base of an NPN TR 114 through N-channel MOSFET arrays 111, 112 and the TR 114 is turned on, the drain level of the P-channel MOSFET 110 is decreased to an L level and the level is logically inverted by an inverter 116 and the level of an output line goes to an H level. When any of the 2nd - n-th signals goes to an L level, the drain level of the P-channel MOSFET 110 goes to H level by a pre-up means, the level is logically inverted by the inverter 116 and the level of the output line goes to an L level. Thus, since the switching is implemented by the bipolar TR, high speed switching is realized.
