The ZN416E can be configured as a simple 455-kHz IF amplifier. In this case, the circuit's center and bandwidth are set by RES1 (a Murata CSB455E ceramic resonator). The ZN416E is a versatile integrated circuit designed for use as a...
Due to the recent launch of Cranial Electrotherapy Stimulation (CES) portable devices in Europe, a similar circuit has been designed for hobbyists. CES is a widely used method for electrically enhancing brain function and has been prescribed by medical...
The 555 timer generates a rapid series of pulses when switch SI is in the open position. These pulses are grouped into sets of 16 and converted into binary format by the 7493 counter. The binary output is then...
The FM24C256 is utilized as a slave interface circuit in an I2C bus configuration, with the address format specified in Table 27-3. The address pins A2, A1, and A0 are set to low; however, for extended storage capacity, adjustments...
A time delay circuit utilizing a Unijunction Transistor (UJT). The maximum time delay is adjustable via a 10 MΩ potentiometer, allowing the time delay to be configured from less than one second to approximately 2.5 minutes, as referenced by...
A varying brightness AC lamp circuit utilizes a silicon-controlled rectifier (SCR) to gradually adjust the intensity of a 120-volt light bulb by controlling the duration of AC line voltage applied to the lamp during each half cycle. The circuit...
