The wireless module is actually a pair of wireless receiver and transmitter circuits. There are only few frequency bands (ranges) which we are allowed to use legally. One of those frequencies is 433Mhz. Based on 433MHz transmission frequency, we have the transmitter and the receiver circuits as TX433 and RX433. The transmitter and the receiver […]

Q: Implement the Octal to Binary encoder
Q- Implement the Octal to Binary encoder (only first 8 numbers). Ans: In this circuit, we have 8 inputs and 3 outputs. The octal number is feed into the encoder by placing a high (1) on the corresponding line and we get the binary equivalent as output. From the above truth table we can easily get […]
Encoder
This digital circuit does exact opposite of the function of a decoder. It converts the information from 2 n to n lines. The truth table is: We can easily design the circuit diagram from this table. How ever if mistakenly we have ‘1’ at two of the inputs then we’ll have wrong answer from the circuit. But […]
