Consider an input signal with two independent channels. Each channel contains three symbols. The data in each symbol consists of four samples.

s = rng;
rng(68521);
n = 4; % Number of samples per symbol
ch1 = randi([0 1],3*n,1); % Random binary channel
ch2 = rectpulse([1 2 3]',n); % Rectangular pulses
x = [ch1 ch2]; % Two-channel signal

Integrate this discrete-time signal. After integrating, each column in the signal corresponds to one channel, and each row in the signal corresponds to one symbol

y = intdump(x,n)
y = 3×2

Input Arguments

collapse all

Discrete-time input signal, specified as a scalar, vector, or matrix. When the input signal is not a scalar value, it must contain k-by-n rows for a positive integer k. For these input signals, the function processes each column independently.

Data Types: double

Integration period in samples, specified as a scalar. The function resets the sum to zero after every n input samples.

Data Types: double

Output Arguments

collapse all

Average of the discrete-time input signal over an integration period, returned as a scalar, vector, or matrix. If the input is a k·n-by-h matrix, the output is k-by-h.

Data Types: double
