1.	Transorthogonal code is obtained by(a) Deleting last digit of each orthogonal codeword(b) Deleting first digit of each orthogonal codeword(c) Doubling each digit of orthogonal codeword(d) Taking negative of each digit of orthogonal codewordThe question was posed to me in an interview for internship.My doubt is from Waveform Coding topic in chapter Channel Coding of Digital Communications
Answer» CORRECT option is (b) DELETING first digit of each orthogonal codeword The EXPLANATION is: A code GENERATED from an orthogonal set by deleting the first digit of each codeword is called as transorthogonal code or SIMPLEX code.
