Both the majority of class B or AB power amplifiers currently encountered in HI-Fi amplifiers are presented in the form of integrated circuits specifically designed for this purpose. It is interesting for technicians to know how this type of amplifier works, if only out of intellectual curiosity. The provided model allows the study of several […]
Newly Updated Circuit Projects:
Convert any Existing AC Lamp into Timer Controlled Lamp
The proposed push button timer circuit module can be directly integrated with any existing switch contacts of a lamp and enable the lamp to be converted into a timer controlled lamp. A common problem arises whenever one wants to replace a mains AC lamp controlled by a switch with a timer or a time switch. […]
