Light control sensor switch

Overview

Circuit description: This circuit is an emitter follower composed of a photoresistor and a transistor. When the resistance of the photoresistor changes, it is converted into the voltage of the base. The voltage of the base is "transmitted" to the emitter, thereby controlling the brightness of the emitter LED. The reserved p2 interface can give high-level signals to the microcontroller to control other circuits, and can also be used with other modules through lead wires. It has a wide range of use, strong applicability, all-hard components, low cost, long life, etc. Features.

How to deal with the cases where no translation is done?
If the low-order address (A0-A11) is connected to the address pin of the memory chip, the high-order address (A12-A19) is decoded for chip selection (where A14 and A16 are not involved in the decoding
Wideband filter
Could an expert please tell me what a broadband filter is? Does it mean that the input signal bandwidth that can be processed is very wide or does it mean that the output bandwidth is wide?
