Basic Electronics 08 – Reading value, tolerance and power rating of resistors
In the previous article, we presented a resistor selection reference table. With the help of this table, you can determine which type of resistor will be most suitable for a given circuit or application. Once you’ve determined which type of resistor suits the best, it’s time to pick up the desired resistor. For that, it…
FSK Modulators using IC 555
FSK means Frequency Shift Keying. It’s one of the Modulation Scheme used to Transmit Digital Data using High Frequency carrier signal. In this Modulation Scheme bit 1 is transmitted using one carrier signal and bit 0 is transmitted using another carrier signal like· Bit 1 (logic high) is Transmitted using Carrier Frequency Fc1· Bit 0 (logic low) is Transmitted using Carrier Frequency Fc2It means Series of bits (bit stream) are transmitted with two different carrier signals used for bit 1 and bit 0.
High Current Variable Power supply
The popular Variable voltage regulator IC LM317 can handle only up to 1 ampere current and hence it is not suitable for making a high current variable power supply. This circuit uses IC LM138 to make 1.25 to 28 volts variable power supply with a current up to 5 amps. Circuit working LM 138 is…
