Category: Security Circuits / Safety Circuits Views: 1615 Rank: 0 This is an opamp version of the synchronous modulator I submitted earlier. It has more consistent performance over varying power supply voltage than the discrete version, but it still has the 0.7 Vp-p limitation on the maximum input voltage.You should use a JFET or a CMOS switch in place of Q1 if you need to accommodate a higher input voltage. Also, a low pass filter needs to be added after the output of this circuit, where the discrete version had one built in. visit page.

Related circuits Fingerprint based attendance system with 8051 This project gives you a fingerprint based attendance system with 8051 microcontroller. The SM630 fingerprint module is used for fingerprint matching. It can store a max of 768 fingerprints. The admin can add/delete records from the PC through the VB application. There is an infrared LED and... This circuit checks the reliability of appliances so that the equipment may be used safely. The test circuit must be plugged into a properly wired three terminal wall outlet. When a two-lead or three-lead appliance is plugged into circuit outlet SOI, neon lamps NE1 and NE2 will light if the... Amplifier input signal overdrive auto-protection That circuit protects the overdriven signals going into an amplifier. Instead of a zener diode we use a transistor. That way we ensure that the above the ordinary input voltages ( 1 volt r.m.s.) can be acheaved without distortion. Also the use of a transistor limits the number of components... Because of the finite hold-on time of delay circuits Rl/Cl and R2/C2, both SI and S2 must be pressed at the same time These two circuits are SSB generators. One uses a crystal filter by KVG Electronics at 9 MHz, the other uses a 455-kHz mecha Industrial applications sometimes require that power be only briefly applied to a load following the closure of a switch, such as a microswitch or foot switch. The load could be a heating element for use in sealing plastic bags, a de motor that is indexed or stepped with each application of... The reader mechanism shown was purchased from All Electronics for $1.50. The unit provides the magnetic head on a spring mechanism along with low level head signal amplifiers and data slicers. Three signal lines comming from the unit provide card presence, clock, and data. When actively... This circuit uses a type 741 op amp as a voltage comparator. One input of the 7.41 is connected to a reference voltage (a 12-V battery) through a resistor voltage divider. The potential at the noninverting input of the 741 is approximately 3 V. The inverting input of the op amp comparator is... Lecture 24 - DESIGN OF SYNCHRONOUS SEQUENTIAL CIRCUITS
