A square matrix A is orthogonal when $AA^T = I$ where $A^T$ is the transpose of A and I is the identity matrix. Let $O_n$ be the set of $n \times n$ orthogonal matrices. a) Establish that $O_n$ is a subgroup of the invertible $n \times n$ matrices $GL_n$. b) Show that the determinant of an orthogonal matrix is either 1 or -1. Suggestion: Recall the homomorphism property of the determinant: $\det(AB) = \det A \det B$. c) Let $SO_n$ be the orthogonal matrices whose determinant is 1. Show that $SO_n$ is a normal subgroup of $O_n$. d) Describe the quotient group $O_n/SO_n$. Use the first isomorphism theorem to find a group to which the quotient group is isomorphic.

The data stream [11011011, 10110111, 10011000, and 10101010] is generated using PCM system with non-return to zero (NRZ) line coding. This frame of data can be transmitted over 150KHz channel bandwidth (BW) if no any error detection and correction methods are used. A) If VRC&LRC parity are used together, write the new frame, and calculate the required transmitted channel BW. B) Use the following polynomial (p)=(x^(3)+x+1) to calculate the data transmitted for the (last sample only) by using cyclic redundancy check (CRC), then calculate the required transmitted channel BW for the entire new frame by assuming that the same number of CRC bits are added to all samples?L correction methods are used. required transmitted channel BW. the (last sample only) by using cyclic redundancy check (CRC), then calculate the
