Mathematical Conventions

• Time-domain versus frequency-domain signals:

  x(t)	time-domain signal
  	frequency-domain signal

• Continuous versus discrete-time signals:

  x(t)	time-domain signal
  x[n]	time-domain sequence

• Statistical signals:

  ε[.]	expectation
  mx	mean
  	variance
  Rxy(τ)	cross-correlation

• Complex signals:

  | . |	modulus
  	angle
  	real part
  	imaginary part

• Vector and matrices:

  v	vector
  	matrix
  	square matrix of size N
  	matrix of size M × N
  	element of located at row i and column j
  matrix of zeros
  identity matrix
  Fourier matrix
