RE📌PULSE AMPLITUDE MODULATION
Pulse amplitude modulation is the simplest form of modulation. It is an Analog to digital conversion method where the message information is encoded in the amplitude of the series of signal pulses.
Pulse amplitude modulation is a technique in which the amplitude of each pulse is controlled by the instantaneous amplitude of the modulation signal. It is a modulation system in which the signal is sampled at regular intervals and each sample is made proportional to the amplitude of the signal at the instant of sampling. This technique transmits the data by encoding in the amplitude of a series of signal pulses
🔶️The pulse amplitude modulation can be generated through 555IC by connecting one NPN transistor at the output. The connection of this IC can be done in the astable mode for producing a pulse train so that samples of the audio signal can be obtained.

CHThink of SOLID as rules to write clean, flexible and maintainable code👇
🟢 S — Single Responsibility Principle (SRP)
One class = One job
Definition: A class should do only one job.
Analogy: Like a coffee machine — it only makes coffee , not toast .
Example:
• ❌ Don’t mix “order handling” and “email sending” in one class.
• ✅ Create separate classes: OrderService, EmailService.
🟢 O — Open/Closed Principle (OCP)
Open for extension, closed for modification
Definition: You should add new behavior without changing old code.
Analogy: Power socket — you can plug in new devices without changing the socket.
Example:
• ❌ Editing core payment logic to add UPI.
• ✅ Just add a new UPIPayment class that follows the existing interface.
🟢 L — Liskov Substitution Principle (LSP)
Child should behave like parent
Definition: A child class should work wherever its parent class works.
Analogy: Any car should be drivable, whether it’s petrol or electric.
Example:
• Car.start() works
• ElectricCar.start() should also work
❌ If ElectricCar can’t start → LSP is violated
🟢 I — Interface Segregation Principle (ISP)
Definition : Don’t force a class to implement methods it doesn’t need.
Analogy: A camera shouldn’t be forced to make phone calls.
Example:
• ❌ One giant “Device” interface with print(), scan(), fax().
• ✅ Split into Printer, Scanner, Fax interfaces separately.
🟢 D — Dependency Inversion Principle (DIP)
Definition: Depend on interfaces, not on concrete classes.
Analogy: Like plugging a charger into any wall socket — not hardwiring it.
Example:
• ❌ Code depends directly on MySqlDatabase
• ✅ Code depends on Database interface
✅ Easy to replace, mock, and test.
